Not a direct answer, but this seems to be the PR for adding PS5 support to Mesa: https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/40..., seems it's just oneline change of AMDGPU_GFX1013_RANGE, not sure if it's a UI bug or what.

It has an AMD RDNA2 GPU. It might have some small specializations but it’s going to be 99% the same as other RDNA2 GPUs.

Look up the BC-250, it is the PS5 but was created for mining. You can get these very cheap on eBay.
