Intel's New Chimera: Alder Lake
I very much don&#x27;t understand why Intel didn&#x27;t disable AVX-512 on the P cores, unless and until the OS writes to a new MSR that means &quot;I understand that the P cores can do AVX-512, while the E cores cannot&quot;, and then enable AVX-512 on the P cores.<p>Old OS versions continue to work fine, and newer OS versions can opt into the new world and benefit.
