From PC World: Intel is planning to offer a version of its hybrid Alder Lake chip—without efficiency cores—and AVX512 is indeed dead on 12th gen.
The company confirmed with PCWorld that AVX512 would not be present in its upcoming 12th-gen chips, which now moves the controversial instruction set back into the dead column—cue your Monty Python memes.
A gaming software developer guide that Intel published last week indicated that AVX512 would be in Alder Lake. This differed from the company’s previous statements that the feature—while present in the actual cores—would be permanently turned off so as not to confuse operating systems.
Company officials had said that AVX512 was in the Alder Lake performance (P) cores but not in its efficiency (E) cores, so to present a uniform face to the OS, the company was fusing off the feature to remove it permanently. The subsequent gaming guide, however, said that AVX512 would be present if the E-cores were turned off on a system. The developer’s guide has since been removed while being updated.
