> I am curious about the specs, but honestly don't care much.
The specs seems to be leaked here <https://thegamepost.com/nintendo-switch-2-full-specs-appears...>
TL;DR
- CPU: Arm Cortex-A78C 8 cores Unknown L1/L2/L3 cache sizes
- GPU: Nvidia T239 Ampere 1 Graphics Processing Cluster (GPC) 12 Streaming Multiprocessors (SM) 1534 CUDA cores 6 Texture Processing Clusters (TPC) 48 Gen 3 Tensor cores 2 RTX ray-tracing cores
- RAM: 12 GB LPDDR5
That spec seems fishy given both Ampere and Ada both have 1 RT core in each SM. 12 RT cores would make much more sense. The 1534 Cuda cores is also weird since 128x12 would be 1536. ALSO the leak says "Nvidia T239 Ampere (RTX 20 Series)" but Ampere debuted in the RTX 30 Series.
The leaks are a little inconsistent on this one.
On one hand, the base architecture is Ampere, but it's been repeatedly rumored that there are various backports from Lovelace. It's a weird mixture of the two, alone with some unique parts never seen elsewhere (a file decompression engine that accelerates LZMA, according to kernel commits).
It's hard to say then how powerful these raytracing cores are, or how many are even necessary for simple but beautiful effects. It's also worth remembering that the Switch bakes the graphics drivers into the game itself, uses data structures and shaders more native to the GPU without compilation, and has a custom low level graphics API called NVN (and NVN2), so performance is not necessarily linear compared to a PC.
Only 2 ray-tracing cores makes you wonder why they’d even bother.
Any actual game devs wanna chime in on whether that’s enough to actually do any ray tracing?
