how many apps using avx-512 in first place?
console emulators?

the only reason why intel disabling it because the small cores dont have those instruction set.
so to avoid incompatibility, they just axe the feature instead.

even the upcoming raptor lake wont have it too.

the use case is really niche, doubt that will bring tons of advantage for amd if they decide to support it.
i rather manufacturer just focus improving existing SSE or avx/avx2 performance instead. amd for example can start experiment with their own 6 wide decode front end

well duh, its a wider instruction.
for sure power usage per clock increase a bit.

so whoever that have 12700-12900k/kf chip is considered a collector item or not?

come, im willing to trade my 12700kf with a faster processor that have this avx512 hardware removed.
