Intel is set to disable AVX-512 on its 12th Gen CPUs

Intel is set to fully disable the AVX-512 instruction set on its entire Alder Lake CPU range. Prior to writing our launch reviews, we had no reason not to believe Intel when it claimed that AVX-512 was not available on 12th Gen CPUs. It wasn’t long after though, that motherboard manufacturers and users discovered that the omission of AVX-512 turned out to be a soft lock. Disabling the E cores meant that motherboard manufacturers could enable AVX-512 on the P cores via the BIOS. Intel has come over the top though, meaning it will be sayonara to AVX-512 on Alder Lake for good.

According to Igorslab, Intel has advised motherboard manufacturers that it will block AVX-512 support at a BIOS level, likely through a microcode update. That means any of the workarounds discovered up until now will be null and void.

Chris' gaming experiences go back to the mid-nineties when he conned his parents into buying an 'educational PC' that was conveniently overpowered to play Doom and Tie Fighter. He developed a love of extreme overclocking that destroyed his savings despite the cheaper hardware on offer via his job at a PC store. To afford more LN2 he began moonlighting as a reviewer for VR-Zone before jumping the fence to work for MSI Australia. Since then, he's gone back to journalism, enthusiastically reviewing the latest and greatest components for PC & Tech Authority, PC Powerplay and currently Australian Personal Computer magazine and PC Gamer. Chris still puts far too many hours into Borderlands 3, always striving to become a more efficient killer.
