The purported Switch revision - which is rumored to be launching sometime around Christmas this year - will allegedly be powered by Nvidia's next-gen Ada Lovelace architecture according to reputable Twitter leakster kopite7kimi. Ada Lovelace is rumored to be the successor to the Ampere architecture that powers the current generation PC GPUs from Nvidia. This alleged development isn't too far-fetched considering the fact that the Maxwell GPU architecture inside the Tegra X1 and X1+ SoCs powering the Nintendo Switch and the Switch Lite is seven years old now and does not support cutting-edge technologies like DLSS which the Switch revision will reportedly feature.
The mention of Ada Lovelace happened for the first time in December last year when it was said that Nvidia was delaying its rumored Multi-chip Module (MCM) design dubbed 'Hooper' in favor of the new 5nm Ada Lovelace architecture. With this next-gen design, it is alleged that Nvidia will be nearly doubling its CUDA core count to 18,432 up from 10,752 in current-gen Ampere. Of course, it is unlikely that a handheld console like the Switch, no matter how powerful the revision may be, comes with something as beefy as that. But a variant of the Ada Lovelace design which is cut-down and custom-built for the revamped 2021 Switch is more than plausible.
