I'm pretty sure it's just vanilla ARM NEON so I don't think it will take any reverse engineering. The Apple Silicon GPU is custom, but the CPU is just minor extensions to (and compatible with) AArch64. Rumour has it that this is because AArch64 was designed by Apple and donated to ARM (who Apple has close relationship with being that they were a founding member).

Apple support NEON (and uses it for most SIMD code) but it also has other proprietary ISA extensions for e.g. matrix multiply.

Interesting, that's what I was curious about. NEON is a bit slow last I checked, but at least Apple is sticking to spec here. It does make me wonder how much performance is left on the table for ARM architectures that want to emulate x86, though.

...it also raises the question of how emulated titles fare against translated ones. It would be fascinating to see how something like Dark Souls Remastered performs through Yuzu vs DXVK on Apple Silicon.

note that the proprietary extensions are extremely unlikely to gain linux support though, unless upstream arm adopts something similar

though amx won’t help out with emulation much
