Intel permanently eliminates AVX-512 support on Alder Lake

As we have reported over the last few months, some motherboard manufacturers have offered the option of using AVX-512 instructions, disabled by default, on Intel's Alder Lake family processors. This would have allowed the CPUs to pass the appropriate benchmarks (e.g. y-cruncher) much faster than models without the AVX-512 activated. However, Intel has decided to permanently eliminate this possibility.



Indeed, an anonymous source has reported to colleagues in the American division of sportsgaming.win that the new batches of “non-K” processors "Seem to have AVX-512 support completely disabled, as an internal fuse has been blown which physically eliminates the possibility of carrying out these instructions, definitively closing the matter.

This is why many motherboards initially shipped with a microcode with AVX-512 enabled, something that caused some confusion and required Intel to issue a new default microcode that "permanently" disables the technology that, however, it has been bypassed by some manufacturers, such as MSI.

In case you need the AVX-512, you will necessarily have to upgrade to more expensive products, such as the Xeons, but it seems that AMD is also willing to implement these instructions in its future Zen 4 chips.

Yesterday we told you that Italy seems very intent on convincing the American giant to open factories in the Bel Paese. For more details, we advise you to read our previous dedicated article.
