Intel now deactivates AVX-512 capability on new Alder Lake CPUs
And that would be fused on a hardware level. Whilst AVX-512 was not officially supported on the chips, it was useable on Alder Lake on several motherboards.
According to an unnamed source, AVX-512 has been fully disabled in recent editions of Intel's Alder Lake non-K CPUs. This was later confirmed by Intel. "While AVX-512 was not fuse-disabled on select early Alder Lake desktop devices," a company official informed Tom's Hardware, "Intel expects to do so on Alder Lake products in the future."
Most 600-series motherboards later received an upgrade that eliminated official support for AVX512. Surprisingly, several firms attempted to provide partial support via secret BIOS settings. However, this is expected to change shortly, since the revised Alder Lake silicon will no longer have this area of the device physically activated. If you want AVX-512 capability with Intel's latest designs, you'll have to upgrade to its more costly Xeon CPUs. Meanwhile, AMD is said to be adding AVX-512 support to its Zen 4 processors, which is an unusual twist if Intel continues to refuse to support the instructions on consumer devices.

Sort of. It's more like an anti-roll bar getting removed - it isn't really a big deal in day to day driving but it definitely will have an impact in specific situations. But even then, that's stupid, because hardly anything needs AVX512. It's a feature that adds a great deal of complexity and expense to a chip, so, it really seems like poor insight if they felt the need to disable it.
What a dick move, that's like selling a sports car base model and disabling the turbo charger on the engine AFTER you sell it with it running.

And we have even activated it again on the latest Asus 1302 beta bios that came yesterday, on old 12900k
My spare 12900k's will be worth like gold for PS3 enthusiasts
For people that don't know: You need to disable e-cores to enable avx-512. So you need to be abit enthusiast to do so :p

Avx 512 was never official supported...
People wanting avx512 is already using it. People that never will use it, is crying for no support LOL
Intel should go frack them selves! If the silicone has it, then it should be enabled!

Sony got sued when they removed otherOS from the PS3.
Intel just does not know how to be decent.
