Intel has released 12-generation Core Alder Lake desktop processors

January 4,2022: Intel has released the 12th generation Core Alder Lake desktop processor, which adopts P+E large and small core architecture for the first time, among which P large core supports AVX 512 instruction set, while small core does not. In an earlier BIOS for the Z690 motherboard, users could turn on support for the AVX 512 instruction set to improve performance in specific applications.

According to Igor's Lab, Intel has been urging motherboard manufacturers to remove support for the AVX 512 instruction set from the Alder Lake processor through BIOS updates.

Foreign media said that removing support for this instruction set is expected to be Intel's desire to limit the use of civilian CPUs in professional computing and distinguish them from workstation processors and server processors.

It is understood that although some of Intel's civilian processors support AVX 512 and AVX2 instruction sets, running such instruction sets during running tests will greatly increase CPU power consumption and will not be able to run at full load for a long time. Intel processors turn on AVX2 throttling by default, which strictly limits power consumption, but some ASUS motherboards provide an unlock option in the BIOS that allows the processor to run AVX2 computing without power limit.
