AVX-512 can benefit the average Joe, it appears.

Sadly, Intel takes another loss here.

There is an issue, though: Intel disabled AVX-512 for its Core 12th, 13th, and 14th Generations of Core processors, leaving owners of these CPUs without them.

I'm surprised Intel would remove a feature that AMD provides in their desktop CPUs.

Probably some BS market segmentation move.

I imagine they noticed only certain server customers were using those extensions, so decided to limit them to high margin server SKUs.

It would have been a smart move if there weren’t competitors putting that instruction in every CPU.
