Sources have reportedly told Digital Foundry that the custom Nvidia T239 chip rumored to be in the next iteration of the Nintendo Switch does not include deep learning accelerator (DLA) capability, which may have a big impact on its DLSS upscaling capabilities. With DLA, DLSS upscaling would effectively be "free," or at least require quite a bit less CPU power. Without it, the Switch 2 may be limited to 1080p, or "possibly 1440p if you're lucky, depending on the game."
These estimations are based on broadly equivalent hardware and remains far from confirmed. However, it potentially puts a dent in the Switch 2's capabilities, which have been rumored to be in the range of the Xbox Series S.
DLSS (which stands for Deep Learning Super Sampling) has been at the center of the rumors swirling around a potential Switch 2 for over a year now, with the first references to DLSS and the Tegra 239 graphics chip as potential Switch 2 features popping up in the massive NVIDIA hack that occurred in March 2022. Earlier this month, Digital Foundry published a detailed deep dive into the rumored custom processor and its likely capabilities.
Woopah is right. You guys are talking about DLA without even knowing what it is. DLSS runs on the Tensor Cores (which the T239 for Switch 2 has (48 of them to be precise)). DLA is a fixed-function hardware that is only present on the Orin/Xavier SoC's Nvidia has for automotive/AI edge/Robotics etc. It's not present on Nvidia GPUs for desktop or mobile...
Someone wrongly told Rich that Nvidia kept the DLA hardware from the Orin SoC (and thus why he cited the DLA possibility on his video testing PC specs for switch 2), but we know that the T239 is a very customized SoC, with many blocks from the Orin SoC (T234) being removed, and we already knew for a long time now that the DLA block wasn't present.
So, just to be clear, DLSS runs on Tensor Cores, which the Switch 2 will have, and normal nvidia GPUs don't even have DLA hardware. Also, there's absolutely no evidence that DLA could even help with DLSS. Maybe it could, we just don't know.
With all that said, with switch 2 having 48 Tensor Cores, there probably will be compromises. DLSS isn't free. But for that we can only wait and see.
