Although the avx-512 instruction set is mixed, it has always been a trademark of Intel. AMD zen4 Raptor 7000 series should learn from its AI acceleration instructions. However, in its core processor products, Intel's support for avx-512 has been wavering. In particular, the 12th generation core probably introduced a hybrid architecture, and avx-512 is even more mysterious.
Access:
In the earliest developer guidance, the big core of the 12th generation core desktop version clearly indicated that it supported avx-512, but then Intel made changes to emphasize that this generation did not provide avx-512.
After the release, generation 12 core was quickly cracked, enabling avx-512. Some motherboard manufacturers also publicly provide support.
Unfortunately, in March, intel was a killer, shielding the support of generation 12 core for avx-512 from the hardware level, and there was no possibility of cracking.
If you really need to run the avx-512 instruction set on the 12th generation core, there is a very simple way to find the batch that supports it. That is to look at the Intel logo on the surface.
As shown in the above figure: if the logo is circular, it is the batch produced in 2021. It is supported and can be cracked; If it is square, it is 2022. It is not supported**
In fact, many users still think that this square logo is a fake when they see it. However, this is part of Intel's overall replacement of the logo in September 2020, and the style is more square.
