It's fair to assume that Intel was not happy with the continued trickery, and now the company is disabling AVX-512 in a decidedly immutable manner — no amount of BIOS hacking or trickery will enable AVX-512 on all newer Alder Lake chips. So if you're dead set on using AVX-512 on Alder Lake, you'll need an older chip and will have to stick with one of the older BIOS revisions.

Intel would like you to step up to its more expensive Xeon chips if you want AVX-512 support with its newer architectures. Meanwhile, AMD is rumored to bring support for AVX-512 to its Zen 4 chips, which is an odd twist if Intel continues to not support the instructions on its consumer hardware.

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

Intel AVX-512 can accelerate performance for workloads and use cases such as scientific simulations, financial analytics, artificial intelligence (AI)/deep learning, 3D modeling and analysis, image and audio/video processing, cryptography, and data compression.

Intel succeeded in baiting AMD to support AVX-512 so obviously they pull off the plug

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

An anonymous source tipped us off that newer batches of Intel's non-K processors (models that aren't overclockable) appeared to have AVX-512 support disabled entirely. We followed up with Intel, and the company issued the following statement to Tom's Hardware:

Buy K punya if want AVX-512 - but eventually also tarak

or

Buy server chip

xeon e price actually quite ok ; but dunno mobo price la
