> No one's doing ASM programming on x86 CPUs these days

I take your point, but I think there’s still a fair bit of x86 asm out there. For example, in ffmpeg and zstd.

I don't think anyone really cares about optimizing those codepaths, though.

Try Eigen then, where people were tweaking every last ounce of performance. Even then, it has problems matching MKL or nVidia libs for ultimate performance sometimes.

For systems nobody has used in years?
