  • Your next Apple Watch or smart ring could have a feature that transforms healthcare
    www.zdnet.com
    Kerry Wan/ZDNETBefore there were smartwatches that could call 911 or smart rings that predicted illness, there was the Fitbit, which clipped onto clothing and counted steps and calories.The device launched in 2007 and instantly became a hit among early adopters and fitness enthusiasts. Back then, if a user wanted to view their data, they had to sync the device to a computer to see it on the Fitbit website.Also: The best fitness trackers in 2025: Expert tested and reviewedThat's worlds different from the fitness and health tech circulating today that automatically captures our heart rate and variability as it beats and displays them on a graph with instant insights and recommendations -- or notifies us about our stress levels and then offers breathing exercises to reduce them.The second decade of wearable health techWhile the first decade of wearable health tech was marked by deployment and accessibility -- getting the devices onto as many wrists as possible -- this second decade is more concerned with tracking far more health metrics than ever before and creating more discreet biotech that blends into the background of our day-to-day lives.We see this most poignantly with the dawn of the smart ring, an unburdensome and screenless alternative to the clunky smartwatch that tracks our sleep, activity, and stress. Its battery life lasts days longer than that of most watches.Also: The best smart rings of 2025: Expert tested and reviewedWe're two years away from the 20th anniversary of theFitbit, the first mass-market wearable fitness tracker that fundamentally changed the health tech industry. So, what major improvement will wearable tech's third decade be marked by? These brands give us a few clues.A new take on health monitoringDuring Praveen Raja's presentation onnew Samsung Health app featuresduring the company's annualUnpacked event, Samsung's head of digital health offered a mission statement for the brand's take on health monitoring. "Our vision is to develop a comprehensive system that supports you through every stage of your health journey," said Raja. "From measuring your current health to giving you personalized health insights and coaching, and connecting you with providers and caregivers.Let's break that vision down into two categories: already accomplished and yet to be accomplished. Measuring current health? Check. Its Galaxy Watches and Galaxy Rings do that already. Providing personalized health insights and coaching? Check.Sure, they could keep improving on this one through new features and updates, but it's nearly accomplished. Connecting users with providers and caregivers? This has yet to be accomplished. But Raja implies that this connection between healthcare providers and wearable users is next for the tech giant. Matthew Miller/ZDNETIn other brands, it's already here. Take Withings, the maker of smartwatches, smart scales, and blood pressure monitors. Earlier this month, itunveiled Cardio Check-Up, a feature available for Withings+ members that sends heart rate data collected through a Withings device to a board-certified cardiologist for evaluation and detailed feedback, which is returned to the user within 24 hours.Withings partners with Heartbeat Health Partners, a "tech-enabled specialty care" healthcare company with the largest virtual cardiologist practice in the US, to make Cardio Check-Up happen.The future of health technologyThese partnerships are the future of health technology. And it's not just Withings catching on. Smart ring brand Oura announced in October a "first-of-its-kind" partnership with Medicare Advantage (MA) provider Essence Healthcare.Starting this year, Essence Medicare Advantage members can receive a complimentary Oura Ring and a subscription to the app for health monitoring purposes. In a press release, Essence wrote that it's the first and only MA plan to offer such a setup.Also: Two OTC continuous glucose monitors won awards at CES - and you can try them nowEssence is a value-based care provider, which is slightly different from most healthcare in the US. Value-based care focuses more on patient outcomes in patients over time, with compensation structures that reward providers for healthier populations, compared to fee-for-service care, which compensates providers for each medical service they provide, Oura's VP of Healthcare, Jason Oberfest, explained to me.Oberfest explained that primary care faces many challenges. For one, there are a limited number of clinicians available to support patients, putting further pressure on an already outdated healthcare system. Could wearable technology not only make primary care more efficient for both the provider and the patient but also help providers identify who needs more help? Oberfest thinks so. Nina Raemont/ZDNET"The data from Oura really does help these care teams understand where an individual is in their own health journey and helps them think about ways to discuss improving health choices with the individual they're working with within a care setting," Oberfest said.Oberfest explained that any Essence MA plan member has the option to receive an Oura Ring. Upon setting up the ring, the member is asked if they'd like to share their health information with a care team to receive more efficient care.Also:This smart air purifier with a 'floating' wireless charger is now a mainstay in my homeOnce they opt-in, their data is passed on to the care team. Having such longitudinal and personalized data on hand at a doctor's visit means that the care provider is comparing the data it gathers at the visit to a person's historical averages -- not national averages -- which can help them spot irregularities they may not otherwise, Oura's Shyamal Patel explained to me. When asked if this model -- providing free wearables to healthcare members to monitor their health more efficiently -- could be the future of healthcare, Oberfest said it's a very strong possibility. He also said that while Oura's partnership with a healthcare provider like Essence is a first, the smart ring brand has other, similar partnerships on the way in categories like metabolic, cardiovascular, and women's health. Matthew Miller/ZDNETThere are groundswells of stories on Reddit about people using wearable tech like Oura or the Apple Watch to get a medical professional diagnosis. One Reddit poster recounted how their Oura Ring urged them to see a general practitioner after it recorded heart palpitations and stress peaks. At the doctor, they were diagnosed with an autoimmune disease."I know it's fun to track your sleep and activity, but my Oura Ring has seriously helped me through this challenging period of my life. It helped me get diagnosed (my doctor took the data seriously) and made me more in tune with my body," the user wrote.As much as theAI doomerssay that AI will render medical professionals obsolete, the reality is more collaborative between tech that evaluates health data using AI-embedded wearables and the doctors that provide diagnostics.Apple's FDA-cleared AirPods Pro 2not only function as hearing aids but also offer users a hearing test they can take to their doctor for a hearing loss diagnosis. The same goes for theApple Watch Series 10and itssleep apnea detectionfeature.There is, of course, the question or concern that tech brands and healthcare brands could misuse or fail to protect this customer data or charge people different prices based on the data it collects on them, like how certain insurance companies offer lower rates to law-abiding drivers who install in-car monitoring devices. Given that this is merely a prediction, we don't have the answers to these concerns yet.Wearable medical devices will continue to growAccording to Fortune Business Insights, the market for wearable medical devices is predicted to grow from $91.21 billion in 2024 to $324.73 billion by 2032.This growth comes as the healthcare industry's competitive barriers are eroded by "technology advancements, regulations, data-sharing standards, and empowered healthcare consumers," as Patricia Birch and William Shea write in aCognizant blog poston the industry's challenges.Oberfest says the second decade of wearable tech is less about the simple presentation of data and more about the context the information provides to the user. "It's about helping the individual put that information in context and make better decisions every day as a result of the information," Oberfest said.Health

  • Why I'm recommending the standard Galaxy S25 over the Plus and Ultra this year
    www.zdnet.com
    ZDNET's key takeaways The $799 Samsung Galaxy S25 is for users who want a flagship experience in a smaller form factor. This year's hardware upgrades are fairly limited, but a Snapdragon 8 Elite for Galaxy does improve the battery and camera quality. The camera still suffers from shutter lag, making it less ideal for capturing fast-moving subjects. more buying choices The Samsung Galaxy S25 might not be as flashy as the Ultra, but it's still the best compact phone you can buy right now. It refines an already great formula with a slimmer, lighter design, better battery life, and smarter AI features. But with minimal hardware upgrades over its predecessor, is it still worth $799?Also: I replaced my iPhone 16 Pro with the Galaxy S25 Ultra - and there's a clear winnerIt helps that Samsung is counting on an upgraded Qualcomm Snapdragon 8 Elite processor this year, which not only brings speed improvements but also better image clarity and more efficient battery life -- arguably the three most important aspects for consumers. I've spent the past week testing the device, and while the spec sheet may not excite you, the real-world experience tells a different story. details View at Samsung The Galaxy S25 is slimmer and lighter than last year's Galaxy S24. In fact, it's one of the most comfortable phones I've held and used. Unlike the larger Galaxy S25 Ultra, the flat sides don't feel unwieldy, and the curved edges keep it handy. I'd go as far as to say it offers a better in-hand feel than the Google Pixel 9 and iPhone 16.Also: Samsung Galaxy S25 vs. iPhone 16: I compared the base models that most people should buyOn the front, there's a 6.2-inch AMOLED display with an FHD+ resolution, which, on paper, is less sharp than the QHD+ screens found on the Galaxy S25 Plus and Galaxy S25 Ultra. But in practice, it's still sharp and vibrant for its size. From scrolling through Reels on Instagram to browsing on Chrome to watching movies on Netflix, the Galaxy S25 display delivers a satisfying content consumption experience. Prakhar Khanna/ZDNETI just wish the anti-reflective coating of Gorilla Armor 2 from the Galaxy S25 Ultra had trickled down to this model, as it makes the screen more usable in bright environments. It's a quality-of-life upgrade that would have made the compact phone experience truly one of a kind. That said, the screen is still fairly legible in direct sunlight, as shown in the image above.At Galaxy Unpacked, I had the impression that Samsung was over-relying on the Snapdragon 8 Elite processor to deliver a substantial upgrade over the Galaxy S24 this year. Maybe I dismissed it too quickly because, in my time reviewing the Galaxy S25, I've noticed battery life improvements that I've never seen from the smallest Samsung model.From my tests, the Galaxy S25 lasted me at least an hour and a half longer than its predecessor under similar usage. It's a one-day phone for moderate users -- those who browse, use social media, and message frequently. While navigation and camera use will drain the battery faster, most people will be satisfied with the battery life here.While I like the fact that Samsung has managed to deliver better battery life in a slimmer and lighter design, I'd have preferred a charging rate faster than 25W this year. At least keep it on par with the Galaxy S25 Plus and Ultra's 45W! Prakhar Khanna/ZDNETLike the charging, Samsung hasn't updated the cameras on the Galaxy S25 this year. It features the same optics as the Galaxy S24, which are the same as the Galaxy S23 from the year before. Instead, Samsung continues to lean on the latest processor to enhance its camera hardware, which keeps the devices market-relevant, but nothing more.For a refresher, the camera system includes a 50MP primary camera with optical image stabilization, a 10MP telephoto camera with 3x optical zoom, and a 12MP ultrawide-angle sensor.Also: These useful One UI 7 features are coming to the Galaxy S25 series - and older models tooThe phone offers good dynamic range and consistent colors across its sensors. I've found my image samples to be slightly more detailed than those from last year's model. Samsung has also worked on delivering more accurate human skin tones, along with better low-light results in terms of clarity and lesser noise in challenging environments. 1x, 3x and 5x photos on the Galaxy S25. Prakhar Khanna/ZDNETCompared to the iPhone 16 and Pixel 9, I prefer the Galaxy S25 camera for its versatility. A dedicated 3x telephoto camera is essential for me. However, if your camera usage involves capturing toddlers or pets, the iPhone may serve you better, as these cameras still struggle with fast-moving subjects. Unless you use the Expert RAW app to adjust the shutter speed for all photos, this isn't the best camera system for capturing little humans and furry friends.Some of the biggest camera upgrades come in video mode. You can now shoot log videos with Galaxy Log, enabling cinematographers to apply LUTs to color-grade their 10-bit footage.Also:Every Samsung Galaxy S25 model compared: How to decide which phone to buyThe Galaxy S25 also introduces a new post-editing feature called Audio Eraser, which uses AI to recognize and remove unwanted noises such as wind, water, or public chatter. A similar feature is available on Apple and Google phones, so I'm happy to report that Samsung has finally caught up -- and it works well. Prakhar Khanna/ZDNETThe Samsung Galaxy S25 runs Android 15-based One UI 7, which will soon roll out to the older Galaxy S24 series, bringing most, if not all, of the features I'm about to mention to last year's phones.Starting with AI Select, my most-used AI feature over the past few days. It works like Circle to Search, allowing you to highlight on-screen content and suggest on-device actions based on the information.Also: This $300 Samsung phone looks as good as the Galaxy S25 - at a fraction of the priceFor example, if you receive an event invite via text or email with time, date, and location details, you can tap on AI Select from the Edge Panel, highlight the invite details, and the phone will suggest an "Add to Calendar" option. Tap on it, and the time, date, and location are automatically filled in within your Calendar app.There's also a new Galaxy AI feature called Now Brief, an app-widget hybrid that consolidates important data in one place. In theory, it can show weather updates, suggest taking the day easy if Galaxy Health detects poor sleep, recommend Spotify playlists from your favorite artists, display news and calendar events, and suggest YouTube Shorts. Now Brief Prakhar Khanna/ZDNETHowever, in my experience, it has mostly been a glorified weather app. It couldn't detect my Google Fit data synced with Galaxy Health and didn't show me any news. The suggested Spotify playlists weren't based on my preferences either. Samsung claims the service will improve over time, so I'll update this review if I notice changes.One UI 7 introduces the Now Bar, a new way to display active app notifications on the lock screen. If you have a timer, music player, or navigation running, they appear as stacked cards on the lock screen that you can swipe and interact with.It reminds me of Dynamic Island and Live Activities on iPhones and, in a similar fashion, supports a limited number of apps at launch. I expect it to gain support for more apps as developers integrate it into their products. For now, it feels like a nice feature in its early stages.Also: Samsung Galaxy S25 vs. iPhone 16: I compared the base models that most people should buyOther Galaxy AI party tricks include Portrait Studio for creating 3D cartoons and sketches from portraits, Sketch to Image, and Generative AI for adding objects to photos. These features are more refined and consistent, but tasks like Generative AI and background expansion in the Gallery app can still take more than 10 seconds to process.The Galaxy S25 also includes Gemini AI upgrades. The new, transformed version of Google Assistant can be triggered by a long press of the side button. It allows you to ask for information, plan things, and send WhatsApp messages to contacts. It's better at handling multiple commands in a single line, and I'm looking forward to broader third-party app support.ZDNET's buying adviceWhile it may seem like an underwhelming upgrade on paper, I've enjoyed using the Samsung Galaxy S25. My only gripe is its inability to capture moving subjects well without adjusting the shutter speed in Expert RAW. If you can overlook that, this is a solid phone for $799 -- and an even better deal if you can snag it with a trade-in offer or promotion.Compared to Google and Apple, the Galaxy S25 offers a better display, the best in-hand feel in its segment, a more versatile camera setup, and good battery life. It's better than the similarly priced Pixel 9 and iPhone 16 -- and my top pick for anyone looking for a compact flagship right now.Featured reviews

  • Under Trump, Rule That Bars Medical Debt From Credit Reports Faces Challenges
    www.forbes.com
    WASHINGTON, DC - SEPTEMBER 13: Dana Downey of Pennsylvania speaks at a roundtable on Capitol Hill on ... [+] September 13, 2023 in Washington, DC. Health advocates and community members gathered in Washington D.C. to push for action on medical debt in an event hosted by Community Catalyst, a national organization fighting for race equality and health justice. (Photo by Tasos Katopodis/Getty Images for Community Catalyst)Getty Images for Community CatalystThe Consumer Financial Protection Bureau finalized a rule issued by the Biden administration in January that would bar medical debt from being included on credit reports. The agency estimates the step will remove $49 billion in debt from the credit reports of at least 15 million people. The rule would take effect in March. However, President Trump signed an executive order pausing for 60 days all pending rulemaking activity for federal agencies. This includes the CFPB medical debt rule. He also fired the head of the CFPB, Rohit Chopra. Consumer advocates are worried that Trump and legislators may upend action to reduce debt burdens.The health policy organization KFF estimates that up to 100 million Americans have some form of medical debt, with over 40 million owing around $88 billion. In turn, this affects the credit reports of almost half of the people with medical debt, which can lower their ability to take out loans and be considered creditworthy by lenders.A last-minute effort by the Biden administration to ease the burden of medical debt includes guidance issued in January to curb improper medical debt collections and publish resources to help consumers navigate medical bill disputes.But the rule now faces challenges from the new Trump administration. The guidance has also been criticized by Republican lawmakers, who have said that the CFPB lacks the statutory authority to issue its final rule prohibiting lenders from using medical debt data to inform their credit decisions. Theyve called it a threat to credit reporting accuracy. And, companies that issue credit have also threatened legal challenges, including a preliminary injunction to stop it from being implemented, arguing their members would suffer harm in the form of unrecoverable compliance costs if the rule is not enjoined.Thus far, President Trump hasnt taken action to rescind the rule. But given his desire to shrink government and reduce regulations, hes expected to roll back certain rules. Moreover, Trump just ousted Chopra, the Biden-appointed Director of CFPB.MORE FOR YOUThroughout his tenure, Chopra targeted the financial services industry by spearheading consumer protection regulations, such as capping overdraft and credit card fees on banks, mortgage lenders, credit card providers, payday lenders and others. He worked closely with former Vice President Kamala Harris to address the medical debt crisis, too.In 2022, KFF reporters investigated the financial burdens families face when saddled with medical debt. At the time, it was reported that U.S. medical debt totaled $195 billion. Approximately half of adults didnt have sufficient cash to cover an unexpected medical bill, while 50 million adults were paying off bills on an installment plan for their or a family members care.The situation may have worsened since then, given the increase in the numbers of underinsured. Recent numbers suggest that approximately 43% of working-age adults are inadequately insured. These are individuals who are uninsured (9%), have a gap in coverage during the year (11%) or are insured year-round but have coverage that doesnt provide them with affordable access to healthcare (23%).While the CFPB rule could provide immediate relief if it is not nixed by the Trump administration, the underlying causes of medical debt remain unresolved. Structural deficiencies in the healthcare system include the ongoing problems of un- and underinsurance and high out-of-pocket costs for patients. This raises the question of whether there will at some point be reform to the health insurance systems in America, so as to not just alleviate the current medical debt crisis but also prevent it from happening in future.

  • Digital MinimalismProtecting Kids In An Attention-Addiction Economy
    www.forbes.com
    Group of elementary school students with smartphones.gettyIn 2024, a study published in JAMA Network revealed that reducing childrens leisure screen time to just three hours per week can significantly improve their mental health and behavior. This finding underscores a pressing concern: our children are spending more time on screens than ever before, and it's taking a toll on their well-being.As a digital forensics expert I have examined hundreds of phones and computers in criminal and civil cases. Ive observed firsthand how technology can both empower and entangle us. Excessive screen time is an issue for almost all of us, but it is an especially concerning issue for the developing minds of children, potentially adversely affecting their cognitive development, social skills and mental health.Limiting leisure screen time for todays kids to three hours a week is no easy task. However, by adopting principles from Cal Newport's Digital Minimalism, families can regain control over their digital lives and create a healthier relationship with technology.What Is The Attention Economy?The attention economy refers to how tech companies monetize our focus. Platforms like social media and video games are designed to keep users engaged for extended periods, often at the expense of other activities. For children, this can lead to diminished attention spans, reduced ability to focus on tasks that dont offer immediate gratification, and impaired social interactions.Research supports these concerns. A study published in JAMA Pediatrics found that increased screen time in young children is linked to delays in brain development, particularly in areas related to language, literacy and executive function.MORE FOR YOUDopamine and Digital Addiction: Insights from Dr. Anne LembkeDr. Anne Lembke, a psychiatrist and expert on addiction, explains in her book Dopamine Nation how modern technology hijacks the brain's reward system, flooding it with dopaminethe neurotransmitter associated with pleasure and reinforcement. This constant stimulation creates a feedback loop, making the brain crave more, leading to addictive behaviors.For children, whose brains are still developing, this process can be even more damaging. Constant exposure to instant gratification from screens can lead to desensitization of the dopamine system, resulting in behavioral issues like irritability, impulsivity and anxiety when devices are unavailable.Step One: Recognizing the ProblemThe first step in managing your child's digital consumption is recognizing that the problem exists. Children don't necessarily come out of the womb addicted to technology, but as they grow, their exposure to devices becomes part of their social fabric. The issue is compounded by the fact that children rarely have the internal framework to evaluate whether their digital engagement is helping or hindering their growth.Newports Digital Minimalism suggests that we should ask the key question: Does this digital activity align with my values? Parents should help their children answer this question for themselves. Is spending hours on social media contributing to their development, or is it simply filling a void of attention-seeking behavior? The answer is often the latter, but the awareness of this fact is the first step in taking action.Step Two: Establishing Digital BoundariesNewport emphasizes that digital minimalism isnt about complete abstinence but about intentionality. For parents, this means establishing clear guidelines around device use. Set specific times and places for screen activities, ensuring they dont interfere with family time, meals, or sleep. It's also crucial to model healthy digital habits. Children are keen observers and often mimic adult behaviors. By demonstrating balanced screen use, parents can set a positive example.Step Three: Embrace Solitude and FocusNewport highlights the value of solitude in a world overwhelmed by constant notifications. For children, this is an especially crucial concept to instill. Kids need to experience boredom to develop creativity, empathy and the ability to focus on tasks without external stimulation. A good way to foster this is through structured downtime and activities that promote undistracted engagement.Rather than filling every gap of time with a device, encourage your kids to enjoy activities that require single-tasking. Whether it's drawing, building with Legos, or reading a book, creating opportunities for your children to focus without interruption can help them build the mental discipline necessary to thrive in the modern world.Step Four: Be a Role ModelOne of the most effective ways to teach children about responsible technology use is by modeling it yourself. Children are keen observers, often more influenced by the habits they see in their parents than by the advice they receive. If you are constantly checking your phone, responding to work emails during family meals, or mindlessly scrolling through social media your child is likely to follow suit.As a parent, it's essential to set the tone for balanced tech use. Consider implementing your own version of digital minimalism, setting intentional boundaries around your own device usage, and making more time for face-to-face interaction. Your example will speak volumes about the kind of relationship you hope your child will have with technology.Step Five: Foster a Tech-Positive EnvironmentTechnology, when used intentionally, can be a tool for growth. Newport's minimalist approach advocates for a mindful selection of tools that serve meaningful purposes. Parents should focus on tools that enhance learning and creativity. Coding apps, educational games, and platforms that foster communication with friends and family can all be great ways to use devices to complement rather than dominate a child's life.Technology should be integrated into the family structure in a way that enhances quality time, not detracts from it. Schedule tech-free times but also tech-positive moments, where devices are used to strengthen connections, whether through family video calls with distant relatives or collaborative learning projects.Technology Should Serve, Not ControlThe rise of the attention economy has posed new challenges for both children and parents alike. However, by following the principles of digital minimalism, families can regain control over their digital lives and create a healthier relationship with technology. The goal is not to demonize devices but to use them purposefully, in ways that contribute to personal growth and well-being. By setting intentional boundaries, embracing focused activities, and being mindful role models, parents can help their children thrive in an age of distraction.As Newport teaches us in his work Digital Minimalism, the freedom to choose how we spend our attention is worth the effort, and our children deserve to learn how to wield that freedom early on.

  • Nvidia's RTX 5080 is Actually an RTX 5070 - Wait, What?
    www.techspot.com
    The GeForce RTX 5080 is actually an RTX 5070, or at least it should be based on its hardware configuration. This is the reason the RTX 5080 is so underwhelming: it should be sitting in the 70 class at a lower price point, delivering much more impressive gains generation over generation. Instead, Nvidia has become greedy, and that's what we will be exploring in this article.The reason we can confidently say the RTX 5080 is actually an RTX 5070 in all but name is because not so long ago we explored the history of Nvidia's GPU configurations, dating back to the GeForce 700 series from 2013 (see our feature: Nvidia's GPU Classes Through the Years).We looked at the hardware configurations in each class and compared them relative to the flagship of the era. This allowed us to create a "typical" Nvidia GPU generation an average of what we saw over the last six generations.Now that we know for sure what the hardware of the RTX 5080 and RTX 5090 is, we can slot this into the comparison and see how Nvidia's latest generation is stacking up.Spoiler alert: it doesn't stack up well at all.Evaluating GPU Core ConfigurationsFor core configuration, the RTX 5090 is an impressively large GPU with 21,760 CUDA cores, but the RTX 5080 cuts this down to just 10,752 CUDA cores, and the RTX 5070 is even further cut to 6,144 CUDA cores. This means that the RTX 5080 packs just 49% of the cores seen in the flagship, and the 5070 packs just 28%.Nvidia GPUs: Shader (CUDA) Core CountHistorically, this is quite a weak hardware configuration, even for the RTX 5080. Across the six prior generations, on average, the 80-class GPU featured 72% of the cores of the flagship. Some of the better generations, like the RTX 30 series and RTX 3080, this number was over 80%. The 40 series was one of the weakest showings at 59%, but the RTX 5080 is even worse at just 49%.This actually puts it below the relative configuration of every 70-class GPU in the past six generations, with the exception of the RTX 4070. It's not quite as cut down as the RTX 4070, but the average core configuration across six years for a 70-class GPU is 54% of the flagship.With the RTX 5080, it's just 49%, so you could even make the case it's a 60 Ti-type product. It certainly wouldn't look out of place as a 60 Ti in the 30 series, for example, where the RTX 3060 Ti had 46% of the core configuration of the RTX 3090. That said, in general, the 5080 would usually fit between a 60 Ti and 70-class product.Evaluating VRAMThings don't look much better when examining memory bandwidth. The RTX 5080 has the biggest reduction in memory bandwidth relative to the flagship that we've seen in the 80-class.With the 5090 packing 1,792 GB/s of bandwidth, but the 5080 just 960 GB/s, it has received just 54% of the memory bandwidth. Historically, that puts it below the average from the 70-class, though there are three generations where the bandwidth reduction is similar to what we're seeing from Blackwell.Nvidia GPUs: Memory Bandwidth (GB/s)The RTX 5070 is also shaping up to be a lower-than-60-class configuration, though again, there are some generations where it matches the 60-class.VRAM capacity varies a lot between generations, and there have been some funky configurations over the years. However, again, the RTX 5080 doesn't stack up particularly well, featuring half the VRAM of the flagship model. That's more typically what you'd see from a 70-class card, although the 80-class doesn't always receive substantially more memory than the 70-class.The RTX 5070, with 12GB of VRAM, is more in line with a 60-series product, and that aligns with our general sentiment on the minimum level of VRAM that's suitable for a $550 GPU.Nvidia GPUs: VRAM Capacity (GB)Evaluating GPU PricesLastly, we can take a look at pricing. Now, GPUs are getting more expensive each year, with the flagship model (previously the Titan cards, now the 90-class cards) rising from $1,000 to $2,000 in the space of 10 years. That has also dragged up the pricing of the other models throughout the lineup, but even still, is a $1,000 RTX 5080 a suitable price cut relative to the flagship?Nvidia GPUs: Launch MSRP PricingThis is the only metric where Blackwell is sitting more favorably than the average generation since 2013. Generally speaking, the 80-class card is priced at 60% of the flagship's price, whereas the RTX 5080 is 50% of the price.Now, there are some generations where this aligns the 10 series and 30 series, for example, come to mind where the 1080 and 3080 were roughly half the price of the Titan X and 3090, respectively. But it is a little better than average. Were the configurations also in line with expectations from an 80-series card, the 5080 could be priced at $1,200, but unfortunately, the configuration is well below normal.Similarly, the RTX 5070 is actually cheaper than the historical relative average price of a 70-class GPU. With the flagship now costing $2,000, the 70-class GPU would be more like $750. But again, the 5070 being cheaper than average relative pricing is only good if the configuration is the same as the historical average, which it isn't.Nvidia GPU Configuration SummaryThis summary of the six-generation average Nvidia GPU configuration shows the issue perfectly. The GeForce RTX 5080 has a configuration that would normally sit around or slightly below the level of a 70-class GPU, yet the price is more in line with what is charged for a model between the 70 and 80-class. In effect, this makes the RTX 5080 a slightly worse-than-normal 70-class GPU in its hardware configuration, for which Nvidia is charging 70 Ti relative money.The RTX 5070 has a similar problem. Its configuration is worse than a typical 60-class GPU, probably more around the mark of a theoretical "50 Ti" model, and Nvidia is charging 15% more than typical relative 60-class pricing for it.This mismatch between hardware configuration which drives performance and the price is why most reviewers and many people in the community feel Blackwell is an extremely underwhelming generation.Fixing the RTX 5080Now, there are two ways Nvidia could have fixed this generation to make it more in line with the history of the GeForce series. The first is to adjust the configurations. For the RTX 5080, this would have required a larger GPU die that slots between GB202 and GB203. It would require somewhere around 47% more shader cores, so instead of packing 84 SMs, it would need more like 124 SMs, so 15,872 shader cores.It would also need 43% more memory bandwidth, and the easiest way to achieve that would be increasing the memory bus from 256-bit to 384-bit. This would also allow for a configuration with more VRAM. In return, this configuration would justify a higher price point of $1,200 to be in line with historic pricing trends.Based on the configuration, this properly configured RTX 5080 would be roughly equivalent to an RTX 4090 except priced $400 cheaper, more if you go by street pricing for the 4090.That still wouldn't be a hugely compelling generational uplift relative to parts like the RTX 4080 Super in the range of 35% faster for 20% more money but a lot of that would be due to the increase in price for the flagship model, dragging up the rest of the lineup.At the same $1,000 price point, this mythical RTX 5080 would be quite compelling, and we suspect that's what most people were hoping for RTX 4090 performance for 4080 pricing.This would fix one of the largest issues with the 5070 as we see it right now, which is its 12GB VRAM buffer. Increasing this model to be more in line with the 5080 would see the card equipped with at least 16GB of VRAM.For the RTX 5070, the configuration would need to substantially increase to justify 70-class branding based on historical trends. The 5070 would actually need a slightly larger configuration than the current RTX 5080, though again, the price could also increase to match trends.The second, simpler approach to solving the configuration issue is lowering the price for the existing models and potentially renaming them as well. But let's just go with lowering the price to make things simple.$700 or $800 RTX 5080, Anyone?Based on the hardware configuration of the RTX 5080, it should be priced around 35% of the flagship model, which would put it at $700. That would result in a cost per frame of just $7.69 per frame, a whopping 38% reduction relative to the RTX 4080 Super, making it a highly compelling generation. That would put it on par with, maybe slightly worse than, the cost per frame uplift the RTX 3080 provided relative to the RTX 2080, one of the best recent generations we've had until crypto mining ruined it.Maybe that's a bit too generous for the current GPU market, so maybe $800 is more realistic for this sort of hardware configuration in 2025. That's quite expensive for what is historically more like 70-series hardware, but it would still present a 29% reduction in cost per frame relative to the RTX 4080 Super.Is a Better Configuration or Price Possible?The obvious caveat is that it's become more expensive to produce a graphics card in 2025. Wafers are now significantly more expensive, memory is more expensive, board designs have become more complex basically, everything is more expensive.The obvious caveat that goes with all of this is that it's become more expensive to produce a graphics card in 2025 compared to previous years, especially if we compare back to the GeForce 900 or 10 series eras. Wafers are now significantly more expensive, memory is more expensive, board designs have become more complex basically, everything is more expensive. There is also general inflation to deal with over the last decade.This is Nvidia's primary defense when asked about the rising cost of graphics cards over the years. So the question is whether it's reasonable for 70-class hardware to cost significantly more in 2025 and now be rebranded as 80-class hardware.First, let's explore die sizes. There is some fluctuation over the years with how much GPU silicon is in each product, and how cut down each model is, but the trend has remained relatively similar. The current RTX 5070 die, GB205, is actually the smallest 70-class die we've seen across these seven generations. GB203 used in the RTX 5080 is also smaller than the average 80-class die, but slightly larger than the average 70-class die.Nvidia GPUs: Die Size (sq. mm)The problem Nvidia has faced is that TSMC wafers have become significantly more expensive. Producing 378 sq mm of 4N silicon is drastically more expensive than creating 398 sq mm of 28nm silicon, as was seen in the GeForce 900 series. But does this really explain why the GTX 980 cost $550, the GTX 1080 cost $600, and now the RTX 5080 costs $1,000?We did some calculations based on die sizes, yield estimates slotted into the excellent SemiAnalysis Die Yield Calculator plus rumored costs for various TSMC wafer families. We also set a value for defective dies relative to good dies and assumed that good dies would be needed for each product.Based on this, we came up with a cost of $140 for each GB203 die used in an RTX 5080. To be clear, this is a rough estimate, not the factual cost of the die. It's also obviously not the only component that goes into an RTX 5080 there's also the memory, PCB, cooler, silicon packaging, physical packaging, research and development costs, and so on.Nvidia GPUs: Die Cost Rough EstimateWe also did the same thing for the GP104 silicon that Nvidia used in the GTX 1080 and GTX 1070, built on TSMC's 16nm process, and adjusted for inflation.Our rough estimate for that die is a cost of $40. This means that in the nearly nine years since Pascal, we estimate the cost of 70-class silicon has risen from $40 to $140, a 3.5x or nearly $100 increase.This could be on the higher end of the scale based on the numbers we input into the calculation, but even with more favorable numbers for TSMC 4N silicon, we're still likely looking at more than a 2.5x cost increase.Inflation vs. Hardware Cost vs. GreedThe GeForce GTX 1080 launched at $600 back in 2016, and the GTX 1070 launched at $380. Adjusted for inflation, those prices today would be more like $780 and $500. Then you have to factor in about $100 of additional GPU silicon expenses, plus the added cost of 16GB of GDDR7 memory versus 8GB of GDDR5-class memory, and other associated costs with a more complex graphics card design. This includes needing a cooler and power stages to handle 360 watts, compared to just 180 watts for the GTX 1080 and 150 watts for the GTX 1070.In terms of price increase, Nvidia has raised the price of the model with the full die so GTX 1080 to RTX 5080 by $220 above inflation. And for the cut-down version so GTX 1070 to RTX 5070 Ti we're looking at a $250 increase above inflation. This is ignoring for a moment that a full GB203 configuration is more in line with a cut-down GP104 configuration relative to the flagship.You can see why, from a business perspective, Nvidia wants to charge $200 to $250 more for their latest products compared to nearly decade-old GPUs. The cost of producing graphics cards has gone up, and Nvidia wants to maintain or grow fat margins on each product.What portion is attributed to each of those things is tricky to determine, especially because some of the rise in component prices should be part of the price rise due to inflation, and other parts will be due to expenses outpacing inflation.It's also possible that while the margin as a dollar amount has grown, the margin as a percentage has decreased those Pascal dies would have been very cheap to produce. This is all basic business though: sell more stuff at a higher margin if you can.From a consumer perspective, we see little reason why a relative hardware configuration that used to cost $380 in 2016 or $500 in 2018 now absolutely needs to cost $1,000 in 2025.With all factors included, we think it's reasonable for graphics cards to cost more, but a doubling of the price in less than a decade is unreasonable. It is not costing Nvidia $400 500 more to produce an RTX 5080 now than a GTX 1070 or RTX 2070 in the years prior.The margin on these GPUs is still huge, even if today they might not be where Nvidia wants them to be after all, the margins on those datacenter AI cards still far outstrip GeForce GPUs.Does Nvidia want to sell an RTX 5080 at a price more in line with 70-class hardware? Absolutely not. Could they do so if they really wanted to? Yeah, and probably quite comfortably.They also could have made the RTX 5080 a larger GPU configuration, which would have been more costly to produce, but again, not outrageously so (unless you care only about margins, in which case a $100 150 cost increase is devastating) and if it led to a substantially better product, there would have been more price flexibility.We can look to other parts of the GPU market to see whether this is reasonable too. The Intel Arc B580 uses a GPU die that is similar in size to the RTX 5070, built on a similar TSMC 5nm node, and with a similar 12GB VRAM buffer. Obviously, there are some differences GDDR7 would increase the cost of the 5070, as would the 60W higher TDP.But Intel has priced their GPU at $250, compared to $550 for the RTX 5070. There have been some suggestions that the B580 is being sold for near cost price, and there are stock issues anyway, so it's hard to say it's actually available at $250, but we think you get the picture. Most of the difference in price between the B580 and RTX 5070 is due to margin, not the hardware itself.The other factor in all of this is competition. Nvidia is selling gamers a 70-class configuration for $1,000 because they have no competition. There is no pressure to reduce prices or cut into their margins because the vast majority of gamers buy Nvidia GPUs.They are only competing with themselves in this price range, and based on the GeForce 40 series versus AMD's RDNA3, you could make a strong case they were competing with themselves across most of that product stack. What might force Nvidia to stop creating poor GPU configurations is a compelling alternative, but right now, there isn't one.Shopping Shortcuts:Nvidia GeForce RTX 5080 on AmazonNvidia GeForce RTX 5090 on AmazonAMD Radeon RX 7900 XTX on AmazonNvidia GeForce RTX 4070 Super on AmazonAMD Radeon RX 7800 XT on AmazonAMD Radeon RX 7900 XT on Amazon

  • My family spent $36,000 renovating our home after 35 years. These 7 upgrades had the most dramatic effect.
    www.businessinsider.com
    There wasn't anything special about our old dishwasher.Our new dishwasher is sleek, quiet, and a little higher-tech. Latifah Al-Hazza Our old dishwasher leaked and was loud. In recent years, it also hadn't been cleaning dishes properly, meaning we were doing a lot of handwashing.We'd had it for about 15 years, and early in the renovation process, we realized we were in desperate need of a new one.We upgraded to JennAir's Rise model. It cleans the dishes beautifully with its multiple spray arms but is unbelievably quiet.The dishwasher offers three racks with adjustable components making cleaning dishes after big gatherings much more convenient. Plus, the twist-out filter makes it easy to remove food particles, preventing it from becoming stinky.The coolest feature is that the dishwasher tells us how much time is left and when it's finished by projecting a light onto the floor. It also subtly pops open when it's finished.The windows were a bit of an eyesore.Our old windows tended to get pretty foggy. Latifah Al-Hazza The windows had been in this house since it was built, so it was time for new ones.I never even realized how much of a difference windows can make in a house's appearance until we replaced all of ours.We can see clearly now with our new ones.Our big, open windows give us a great view. Latifah Al-Hazza We hired a company called Window World to come out for the installation, and it was so neat to watch the process.The team of six efficiently staged the layout of the windows, tore out and replaced any rotted wood, measured and bent the metal for the new windows, hung the metal, caulked the trim, and meticulously installed everything.The sizes and shapes of the windows didn't change drastically, but the difference in clarity felt stark. We live on a lake and it's so nice to be able to clearly see the beautiful view.Our fridge was just plain old, and our new one is such a vibe.We now have a very modern refrigerator. Latifah Al-Hazza Our old refrigerator was an eyesore in the kitchen, mostly because it was really showing signs of wear and tear.Plus, it was getting to the point where it wasn't even staying very cold.We upgraded to Samsung's Bespoke French-door refrigerator with a beverage center and built-in water pitcher.It's so pretty that I actually can't stop staring at it.We went with the white finish to help brighten up our kitchen, but it also has changeable door panels in case we ever wanted a different look.One of its unique features is that it can sync to our phones, allowing us to regulate its temperature and know if the door has been left open.Our old couches weren't doing much for us.We had a pair of old couches in our living room. Latifah Al-Hazza Our pair of matching living-room couches were small, and I thought the upholstery was ugly.We'd had them for 27 years, and I rarely ever sat on them.We went with a dramatically different style for the living room.Our new sectional is so comfortable. Latifah Al-Hazza We upgraded to Cozey's Ciello XL seven-seater sectional in sunset beige, which completely transformed the space.It was shipped in individual boxes and was easy to put together. I like that it's fully modular, plus the pillow and seat cushion covers are washable (aka very pet-friendly).The couch has been the most-used item in the house since the renovation.The color is clean and brightens up the room. It's also much larger than our old one, providing ample seating for company.Best of all, it's incredibly comfortable and cozy. I honestly sleep on it more than I sleep in my bed at this point.Our new high-tech oven is such a treat.We upgraded our JennAir oven. Latifah Al-Hazza We'd had a JennAir oven for about 20 years.Even though we loved it, we wanted something with a few more bells and whistles.We wanted to stick with the brand we knew and loved, so we upgraded to JennAir's Rise double-wall oven. For someone who doesn't know how to bake or cook, it's been life-changing.The touchscreen culinary center has built-in recipes with pictures that make it easy to cook and bake anything when I have no idea what I'm doing. I can even select the type of pan I'm using, and the oven will automatically adjust the setting.To be honest, it's the smartest thing in the house.The best part is that I can start the oven from afar and then fully control and monitor it wherever I am via the JennAir app.The kitchen cabinets were a little drab.Our old cabinets were dark. Latifah Al-Hazza We knew our kitchen needed the most renovation out of every room in the house.Our outdated red-oak cabinets were 40 years old, and we never liked that they didn't reach all the way to the ceiling.Our new cabinetry gave our space a facelift.White cabinets can really brighten up a kitchen. Latifah Al-Hazza My mom has always wanted a white kitchen, so she took it upon herself to make it happen.She deglossed the old cabinets to take off all the old varnish. Then, she sanded them down and prepped them for two coats of white paint.She even built smaller cabinets to stack on the old ones to make the kitchen look taller. My mom then ordered small cabinet doors with cutouts from Fast Cabinets and filled them with frosted glass.After months of work, new brushed-nickel hardware and hidden lighting were the finishing touches.I'm actually excited to use our cooktop.The new cooktop is sleek. Latifah Al-Hazza After living with a cooktop that only had two working burners for years, we were plenty fed up.We caved and chose KitchenAid's electric downdraft cooktop.There are two small burners and two larger burners, but the larger ones also have settings to heat smaller pots.My favorite feature is the melt setting. Its sole purpose is to melt things like chocolate or butter without scorching it.Plus, the downdraft fan with three speeds quickly sucks out any smoke produced while we cook.

  • My boyfriend and I adopted a cat. It's been a good test of shared responsibility before kids.
    www.businessinsider.com
    My boyfriend and I recently decided to adopt a cat.We have been discussing our future recently and were excited to share more responsibility.Taking care of our cat together feels like it's helping us prepare in case we decide to have kids.My boyfriend and I adopted a cat to help us understand what it might feel like to take on more responsibility and mentally prepare for possibly having kids. So far, we've been doing a great job keeping plants in the apartment alive and cat-sitting for a few people in our neighborhood.We talked casually about bringing a cat into our lives permanently, but we hadn't gone to any shelters or even thought about what type of cat we wanted. Then, one day, I spotted a post in a local Facebook group from a man looking to rehome his 4-year-old black cat and willing to give the new owner everything they would need: his litter box, food, bowl, and carrier. It just felt right, and within minutes, my boyfriend and I decided this was the cat we wanted to take home.When we adopted Marty, we knew we were taking on more responsibilityWe researched the validity of the post through back-and-forth messaging, some social media research, and even a phone call with the man. He sent through vet records and everything looked right to us. We then confirmed that we had the space and resources to take on this cat, we picked him up and brought him to his forever home.We were nervous at first; we didn't know what he would be like or if he would even like us. We were also unsure how we would split responsibility. But regardless of all these things, suddenly, a black cat we named Marty was in our home and wanted to be fed, played with, and looked after.Adopting our cat was a great test of how we would handle a larger responsibility, like having kids, but on a smaller scale. Who would get up at 5:30 in the morning when he's hungry? Who cleans the litter box? Who will schedule all the vet appointments? It's been a balancing act, a test, and a significant period of enlightenment on how great of a partner my boyfriend is.Taking care of Marty is a two-person job, and I'm glad to be with someone who truly feels like a partner in every aspect of care and responsibility. We divide up responsibility when it comes to who feeds him in the morning and at night, which happened naturally as we took in everything that needed to get done.Usually, whoever leaves to go into the office for work first will feed him in the morning, and whoever works from home will feed him in the afternoon. We take turns washing his dishes and water bowl; we both play with him and scoop his litter box. When we go on vacation, we coordinate with our sitter and ensure he's being looked after.With a cat in our lives, more planning needs to happen than before. Everything requires more coordination, looking at schedules, and ensuring we don't leave Marty alone for too long. We must work around his feeding schedules and disrupted sleep, as he sometimes wakes us up at 4 a.m. to ask for food.We're looking at it like a test run for having kidsHaving a cat has taken our relationship to the next level, adding more responsibility and, naturally, more communication around what needs to be done to ensure he's taken care of. Of course, something that helps distract from the responsibility is how cute and playful Marty is and how much fun he is to have around the apartment.I know owning a cat is not the same thing as having kids. Cats are primarily self-sufficient; you can leave them alone for hours without worrying too much about what trouble they might get up to. While this is true, they also require more planning and thought that didn't exist previously in our lives.My boyfriend and I are both 28 and have discussed the possibility of having kids, what that might look like for our lives, and our future plans. While we aren't in any rush, we're thinking we'll be ready in the next six years. As we gain experience caring for our cat, I feel good about the division of responsibilities we would have if we had kids, and what that might look like for us. In the meantime, we enjoy caring for our cat and spending every day with him.
