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.
