Intel will disable support for AVX-512 on Alder Lake processors.
With a new microcode, Intel seems to be disabling and removing AVX-512 capabilities from Alder Lake CPUs. AVX-512 is currently only supported on Alder Lake through the use of a workaround.
Intel does not promote AVX-512 for Alder Lake, despite the fact that the instruction set was heavily promoted for a couple of its previous-generation client-segment CPUs, especially the 11th Generation Rocket Lake and 10th Generation Cascade Lake-X HEDT processors. AVX-512 is likely to be a feature that differentiates the company's next-generation HEDT processors based on Sapphire Rapids, its future enterprise microarchitecture. Even though AVX-512 is not officially supported on Alder Lake CPUs, software that requires these instructions may be able to operate on certain 12th Generation Core processors when used in conjunction with older versions of Intel ME firmware.
In addition to energy efficiency concerns, Intel's decision to deprecate the few AVX-512 instructions available for Core processors could have been driven by the lack of enthusiasm shown by client application authors for the instructions. In the high-performance computer and cloud computing industries, this command is more appropriate than for the general public.

Same thoughts here, also they used to mock synthetic benchmarks - and all of a sudden they're bragging about CB scores etc.

I remember when intel stole my TSX NI instruction from 4790K. Yes it did because I bought this CPU from tsx ni.
And it gave me an advantage in the RPCS3 emulator, not the benchmark

Not really. I've always seen AVX-512 as nothing more than just a means to make Intel seem like they're not just sitting there doing nothing. It's technology for the sake of technology. It takes up a huge chunk of each core, which contributes significantly toward manufacturing costs. It draws so much power that it makes Intel's performance-per-watt underwhelming, and, cranks up the heat. It's a little too niche to ever be widely adopted.
The only people who were impressed by this are those who like to see more/bigger things on paper but completely ignore real-world results. Granted, AVX-512 has so little real-world impact on today's software that it makes me wonder why Intel cared so much about disabling it.

I think it was a stop-gap effort to compete with GPUs in niche workloads. Intel saw Nvidia/AMD shifting their GPUs for specific compute tasks, they had AVX-512 from larabee/phi - they repurposed and fixed it up and shoved it on their CPUs to try to maintain some relevance of competition in those spaces but ultimately kind of pointless. I think once Intel gets a competitive discrete GPU out, you'll see AVX-512 go EOL.
That being said it does seem nice for the 3 people that are doing like 5 billion layers of audio processing or running PS3 emulators lol

Ironic as it was a good propaganda argument versus other CPU brand that have a lack of AVX-512...
