The Ampere GPU carries the same architecture as Nvidia's RTX 30-series graphics cards, and the die shot shows 12 SMs, which would total 1,536 CUDA cores. For context, that's a little more than half of the cores available in a desktop RTX 3050 graphics card. Geekerwan insists that the closest point of comparison for the Switch 2's SoC is a downclocked RTX 2050 laptop GPU.
I am surprised CDPR is planning to release Cyberpunk on a device with such an anemic GPU. A downclocked laptop 2050 is extremely weak by modern standards.
