Quote:New GNU compiler updates released today (as reported by Phoronix) serve as yet another sign that Intel will release its hybrid architecture, which combines big cores with smaller cores, for desktop PCs when the Alder Lake-S CPUs land.
...
The GNU compiler updates include a list of compatible instructions for both Intel's upcoming data center Sapphire Ridge chips and Alder Lake desktop chips, with the latter noticeably missing support for AVX-512, a SIMD instruction that Intel recently introduced to its desktop chips. These instructions are disabled in Intel's hybrid Lakefield chips to keep the instruction set consistent between cores (Atom doesn't support AVX instructions), therefore easing operating system scheduling routines that target different workloads at the cores best suited for the task. Therefore, the lack of AVX-512 support for Alder Lake could serve as further evidence that Intel will bring its hybrid architecture to desktop PCs.
