> AVX-512

Which subset though? Some of them are not supported by some recent CPUs (e.g. 2024).

Not to mention Alder Lake not supporting AVX512.

Yeah AVX-512 is basically dead as a universal target for x86, the future is now AVX-10. But I believe there is a reasonable subset that will work on both.

It's a little dramatic to say avx512 is dead versus 10 - rather, I would say that avx10 finalizes a universally available set of avx512 extensions. For AVX 10.1, there's essentially, no difference after Intel backed out of reducing the vector length.

For at least the next decade AVX 512 will be the high performance target, reaching all of the zen4/5/6 CPUs as well as whatever avx-10 enabled CPUs Intel producers.
