Fresh Desktop Core CPUs don’t officially support this feature anyway, only motherboard manufacturers have been tricked, but it’s slowly coming to an end.

Last summer we wrote about itthat the AVX-512, perhaps the world’s most vomited set of instructions, got a serious stomach from Intel itself. The company Alder Lake codenamed CPU although its high-performance cores support the system, because its operation required the lower-performance E-core cores to be turned off, the feature was not activated.

Earlier, however we also wrotethat ASUS, ASRock, and Gigabyte, among other motherboard manufacturers, have made the instruction set available. To do this, you first had to disable all E-Core inside the BIOS and then activate the AVX-512 setting, which is inactive by default.
As processors that do not include active E-Core will be added to the 12th generation Core family in the future, users could also activate the AVX-512 with impunity. To prevent users from doing this, Intel has designed a new ME (Management Engine) firmware for its partners that is required to be used alongside the new BIOS. That’s what it is Igor’s Lab reported, and the point of the development is to completely deprive the AVX-512 of Alder Lake processors, meaning it will eliminate the bypasses that motherboard manufacturers have built for unofficial activation.
Since Intel did not pre-list the AVX-512 in the specification for the 12th generation Core processors, it cannot be said that the platform has been deprived of an capability, merely closing the gate leading to access to the unadvertised feature. It is likely that loading the previous microcodes within the operating system would still allow the AVX-512 to be recovered, but there would be so many potential problems with this option that it is not worth bothering with.
