Something to look forward to: AMD has officially confirmed that its Radeon RX 9000-series graphics cards will launch in March, putting an end to speculation about when its latest GPUs will be available for purchase. The RX 9000 lineup will compete with some of Nvidia's recently announced RTX 5000-series cards, headlined by the $1,999 RTX 5090. The announcement was made by David McAfee, the VP and GM of Ryzen CPU and Radeon graphics at AMD. According to his post on X, Radeon 9000-series hardware and software are pretty much baked, and all that remains is the official launch. McAfee also said that the company is planning to have "a wide assortment of cards available globally" when they go on sale this March.AMD unveiled the Radeon RX 9000 cards earlier this month at CES 2025. The lineup includes four SKUs, led by the RX 9070 XT. The three other models are the vanilla RX 9070, RX 9060, and RX 9050. Based on the RDNA 4 architecture, the new products feature AI-powered FidelityFX Super Resolution 4 (FSR 4) upscaling, improved ray-tracing performance, and upgraded media encoding quality.The top-of-the-line RX 9070 XT and RX 9070 include AMD's second-generation AI accelerators, third-generation ray-tracing accelerators, and second-generation Radiance Display Engine. It's unclear how powerful the new 9070 twins are, but promotional material from AMD seems to suggest that they will offer similar performance to that of the Nvidia GeForce RTX 4070 Ti and RTX 4070 Super.AMD hasn't revealed much else about its latest GPUs, but a steady stream of leaks in recent months has revealed some of their hardware specifications and features. According to rumors, the flagship 9070 XT will feature the Navi 48 GPU with 4,096 cores, a 2.97GHz boost clock, 16GB of GDDR6 memory, 256-bit memory bus, 20 Gbps memory speed, and 640 GB/s memory bandwidth.Other critical specs, like the max board power and PCIe interface, remain a mystery. AMD has yet to announce the pricing for any of its 9000-series cards, but they are expected to be priced competitively against the RTX 5070 series. For reference, the vanilla RTX 5070 has a $549 MSRP in the US, while the more powerful 5070 Ti starts at $749. // Related Stories

In a nutshell: Despite being one of the most universal programming languages currently in use for web-based applications, JavaScript remains shunned by a tiny minority of netizens. But Google is now forcing this increasingly sparse group of users to use the ECMAScript-compliant language for searching the internet. Google recently confirmed that JavaScript is now required for users to submit queries to its web search service. According to a company spokesman, the new requirement will improve the overall security of the Google Search service against potentially malicious activities, including bots, spam, and criminals focused on abusing SEO algorithms.The user experience should improve as well, the spokesman stated, because Google Search would barely work without enabling JavaScript first. Bots, spam, and other forms of algorithmic abuse are constantly evolving, the tech giant said, which is why Search needs the full power of the JavaScript language to better protect and serve users.JavaScript's origins date back to the foundational years of the modern web, when Netscape cooperated with Sun Microsystems to add a proper programming language to its Navigator web browser. The "JavaScript" trademark is currently part of a legal quarrel between Oracle and the JS community, but the language is essential for modern, interactive websites and browsers to work the way they do.Some users still avoid using JavaScript for privacy-related reasons, or to improve security online in extremely sensitive environments. JavaScript can definitely increase the attack surface for cybercriminals and adversarial countries, with major browser developers fixing high-severity or critical security vulnerabilities every month.According to Google, the number of average search queries currently served without JavaScript is fewer than 0.1 percent. Google Search processes around 8.5 billion queries every single day, so this tiny minority still amounts to millions of netizens looking for information online without enabling JS first. // Related StoriesAside from being a potential security issue for a non-trivial number of users, the new JavaScript requirement could also have detrimental effects on third-party tools designed to check website rankings on Google Search. A recent report by Search Engine Roundtable stated that some of these tools stopped working after Google decided to enforce the use of JavaScript. The company declined to comment on this report, though a less SEO-oriented search service could be considered a highly desired improvement for those surfing the web.

The ethos of the streaming era is watch what you want, when you want, and that means DVR. Traditionally, with Slings streaming service, that meant getting 50 hours of cloud DVR alongside your base subscription. That meant you would be able to catch up on what you were watching at your leisure and skip through commercials. If you wanted more, you could pay $5 for 200 hours if you used the service a lot.But now the whole thing is getting a lot better. For starters, unlimited cloud storage is coming for just $5 per month, replacing the old 200 hours plan. Plus, you can still get 50 hours of free DVR alongside an additional 10 hours of Sling Freestream DVR storage for free. Tap the button below to check out Sling and pick your plan, or keep reading to see how both the new Sling unlimited DVR works and the free Sling DVR works.The first thing to point out is that DVR storage coming with your Sling subscription isnt going away. Youll still get 50 hours of DVR free, storing your goodies for up to nine months on Slings cloud servers. Sling will give you a nice warning at the one month mark that your programs storage life is about to expire, as well as clearly tell you how much storage you have. When something you have stored is about to go, you wont be able to miss it. In addition to this youll also get an additional 10 hours of Freestream DVR with a 30 day expiration, allowing you to check up on live programming at a time more convenient for you.And while this is all very generous, the big upgrade is getting Unlimited DVR. This service removes the 50 hour cap (and the former 200 hour cap for the paid service) for cloud DVR. Youll still need to watch saved programming within nine months, but youre free to let your backlog get as long as you like. If you decide later to not watch something you saved, its a no harm, no foul situation.At just $5 per month for the service, the hard decision for Sling users will still be choosing between Sling Blue and Sling Orange. So go ahead and tap the button below to get started with Sling today, enjoying free DVR and (should you so choose) possibly unlimited DVR for just $5 a month.

Some thought that AMDs upcoming best graphics cards would be launching in a matter of days, but we now know thats not going to happen. According to David McAfee, vice president and general manager of AMDs Ryzen CPU and Radeon graphics division, the GPUs are doing great and will be widely available but not until March.This delay is an interesting choice, given that some retailers were ready to open preorders on January 22. Multiple listings of the card from all over the world have been leaked at this point, and although we havent seen almost any of its specifications, those listings implied that the cards were ready to go, or at least would soon be available.Recommended VideosRadeon 9000 series hardware and software are looking great and we are planning to have a wide assortment of cards available globally. Cant wait for gamers to get their hands on the cards when they go on sale in March! David McAfee (@McAfeeDavid_AMD) January 20, 2025Get your weekly teardown of the tech behind PC gaming The manner of the announcement was pretty odd, too. After the cards were a complete no-show at CES 2025, AMD implied that the GPUs deserved their own event outside of the 45-minute keynote that also omitted its next-gen Z2 chips. Now, McAfee took to X (Twitter) to quietly reveal that AMDs plans arent so set in stone, and it all comes down to an ambiguous release date sometimes in March.At this point, with Nvidias full RTX 50-series range right around the corner, many AMD enthusiasts expected more. The reaction to McAfees announcement in Twitter replies was lukewarm at best, with many fans wondering where this delay is coming from. AMD and Nvidia are locked in a perpetual battle in the GPU market, and its hard not to give Nvidia the upper hand here, as we know the release date of the first two GPUs, but also the entire spec sheet for all four. Meanwhile, all we know about the RX 9000 series is that itll have 16GB VRAM, but even that comes from leaks.AMD didnt show off the cards during the event, but its partners had them on display during CES 2025, so we know the hardware seems ready to go. AMDs Frank Azor also told the press that the cards were set to launch in a matter of weeks, which still checks out even if its at the end of March, but just barely. Nvidias RTX 5070 and RTX 5070 Ti should both be out by then, with a tentative February release date.Its possible that one of my least favorite leaks may have turned out to be true. A Chiphell forum leaker recently shared that AMD pulled back on the late January release date for the RX 9000 series, citing waiting for Nvidia as one of the reasons. Its hard to say what AMD might be waiting for at this point, but one way or another, we now know for a fact that the RX 9000 series wont be here until March.Editors Recommendations

oh well Californias air pollution waiver and the EV mandate are banned by Trump Among the new president's many executive orders were attacks on clean vehicle policies. Jonathan M. Gitlin Jan 21, 2025 8:19 am | 87 Credit: Anna Moneymaker/Getty Images Credit: Anna Moneymaker/Getty Images Story textSizeSmallStandardLargeWidth *StandardWideLinksStandardOrange* Subscribers only Learn moreUS President Donald Trump swore his oath of office on Monday, ascending yet again to the head of the federal government. As widely expected, he signed a swath of executive orders on his first day, many aimed at upending existing policies and satisfying grievances, whether that's pulling the country out of membership of the World Health Organizationor reversing the nation's clean vehicle policies.The Infrastructure and Investment Jobs Act of 2021 and the Inflation Reduction Act of 2022 were signature pieces of former President Joe Biden's term of office. Among other things, the two bills contained many provisions meant to boost US competitiveness in EV manufacturing and build out publicly funded charging infrastructure.Specifically, the IIJA included $7.5 billion in funding for charging infrastructure. The National Electric Vehicle Infrastructure and the Charging and Fueling Infrastructure programs were modeled on federal highway funding programs, where the funds are disbursed to state departments of transportation, which then award the money to successful applications. NEVI was meant to create corridors of fast chargers along federal highways, and CFI to build out charging infrastructure in underserved areas.That all seems very unlikely now. Trump has ordered the end of the "Green New Deal." He has ordered that all agencies immediately pause any disbursement of funds for NEVI and CFI and that those agencies conduct a review of their policies. If those agencies want to hand out any of that money from now on, they will have to satisfy the new head of the Office of Management and Budget that doing so is consistent with the president's desire to end any favorable treatment toward EVs.EV tax credit and Californias waiverThe executive order "Unleashing American Energy" also kills off former President Biden's goal of increasing EV adoption to 50 percent of all new vehicle sales by 2032. The order claims that it is ensuring "consumer choice" and "a level regulatory field" for vehicle sales.To do this, it eliminates "state emissions waivers that function to limit sales of gasoline-powered automobiles." That spells bad news for California and the 17 other states that follow the California Air Resources Board's Zero Emissions Vehicles regulations. California has been granted waivers under the Clean Air Act to set emissions controls within its state borders, but the first Trump administration spent much time and energy battling CARB's waiver.The previous moves to block CARB's waiver were partially successful and only reversed by the US Environmental Protection Agency just over a month ago.The revised clean vehicle tax credit, which provides up to $7,500 in credit toward the purchase of a new EV, or up to $4,000 for the purchase of a used EV, also looks to be in trouble. The executive order also calls out "unfair subsidies and other ill-conceived government-imposed market distortions that favor EVs over other technologies and effectively mandate their purchase by individuals, private businesses, and government entities alike by rendering other types of vehicles unaffordable." However, as the clean vehicle tax credit is a part of the tax code, changes to it will require Congress to pass legislation to that effect.As you might expect, environmental groups are not impressed. "The transition to electric vehicles is opening factories and putting people back to work across the country," said Katherine Garca, Sierra Club director of the Clean Transportation for All campaign. "Instead of building upon progress weve made, Donald Trump remains intent on fear-mongering around electric vehicles and taking the US back in time while the rest of the world moves forward on auto innovation. Rolling back vehicle emission safeguards harms our health, our wallets, and our climate."Jonathan M. GitlinAutomotive EditorJonathan M.

Wheat is harvested from strips lined by vertical solar panels at the Next2Sun solar park in GermanyKnoblauch GmbH/Next2SunRapid reductions in the price of solar panels mean they are starting to appear in unexpected places, from balconies to motorway embankments. Now, researchers say they could play the role of hedgerows in farm fields, with double-facing solar panels generating power while acting as windbreaks for crops and livestock.Farmers are already installing solar panels, often positioning tilted arrays over crops or allowing sheep to graze between panels. But such installations, known as agrovoltaics, can lead to excessive shading of

Paul Briginshaw/Millennium Images, UKWhats the difference between your time spent in bed and your bank balance? No, this isnt the start of a terrible joke and the answer is less than you might think.We all have the odd occasion when we stay up too late and dont sleep enough. Think of this as the equivalent of splurging on an expensive dinner: you probably shouldnt have, but your bank balance hopefully wont suffer too much.This article is part of special series investigating key questions about sleep. Read more here.But regularly going without enough sleep a problem for many people, with the US Centers for Disease Control reporting that a third of adults there get less than 7 hours a night could have you racking up a sleep debt, with real consequences for physical and mental health (see Why your chronotype is key to figuring out how much sleep you need). Like paying back a financial debt, catching up on sleep takes planning.Part of the problem is that we might not know how much sleep debt we have accrued and how badly it is affecting us. In one study, for instance, participants were randomly selected to get 4, 6 or 8 hours per night for 14 days straight. By the end, those getting 6 hours or less exhibited a cognitive deficit equal to missing up to two entire nights of sleep. However, despite feeling worse after a couple of days, from then on the restricted sleepers didnt necessarily notice their cognitive abilities continuing to decline. The tired brain cant detect how tired it is, says Russell Foster, a
