With the Nintendo Switch 2 Direct creeping up on us along with the rumoured June launch window, rumours about the development kit for the new console have started popping up. A recent rumour revolves around the Switch 2s speculated support for 4K output. Developers have seemingly revealed that the devkit for the Switch 2 doesnt have support for 4K.In a recent episode of the Insider Gaming Weekly podcast, Tom Henderson has said that developers during GDC 2025 told him about the capabilities of the devkits. In these conversation, one developer revealed the lack of 4K output.I heard this from one developer at GDC and also heard it separately in an email, but the dev kits, or some of the dev kits, dont have a 4K output, said Henderson in the podcast.While the lack of 4K output for a development kit isnt too big of a deal in the grand scheme of things, it does indicate that the Switch 2 wont be able to run at such a high resolution natively. Rather, the console will likely make use of some form of AI-based image upscaling in the vein of Nvidias DLSS.This rumoured technology was first spotted back in January thanks to a patent application. According to this, the Switch 2 will feature separate internal hardware to run a neural net. This chip, developed by Nvidia, is expected to be capable of being able to upscale images from 540p to 1080p, as an example.One of the uses of this upscaling technology seemingly revolves around reducing a games overall size. Through this, Nintendo could have the game take up less space on the hardware since the console wont need high-resolution textures that tend to be massive in storage terms, instead relying on image upscaling technology.An example given for this application of the upscaling technology was that, where a game with 4K textures packaged into it might weigh in at around 60 GB, a game featuring texture sizes more suited to 1080p gaming will have a smaller footprint of around 20 GB. The AI-based upscaler can then be used to output the 1080p versions textures all the way up to 4K. This would also allow games to fit inside of Nintendos Switch Carts, which typically have a storage capacity of up to 32 GB.Other rumours from back in January gave us an indication of what kind of horsepower we can expect from the Switch 2. According to these rumours, the GPU on the Switch 2 will clock in at 561 MHz while the console is in handheld mode, translating to around 1.71 TFLOPS (trillion floating point operations per second). Docking the Switch 2 will give it a considerable boost, clocking up at 1,000 MHz, coming in at around 3.1 TFLOPS.The Nintendo Switch 2 is rumoured to be running on an Nvidia Tegra 239 SoC (system on chip). While not quite as strong as the hardware we see in current-gen consoles, let alone modern PCs, the hardware will still end up being a considerable upgrade over the original Switch.
