Intel's next-generation Core Ultra Series 4 "Nova Lake" processors will mark an official return of AVX-512 to the company's client processor lineup. The 512-bit SIMD instruction set will be featured on both the "Coyote Cove" P-cores, and "Arctic Wolf" E-cores, according to Jay Kihn. It is a requirement for both core types to feature an identical ISA, without which thread migration between the two core types will result in runtime errors arising from ISA mismatch.

The last Core processor to feature an official implementation of AVX-512 was 11th Gen Core "Rocket Lake," in which AVX-512 workloads would notoriously cause the 14 nm processor to overheat. Intel would deprecate AVX-512 on all succeeding client microarchitectures, mainly because their respective E-core types didn't support it. Intel is expected to offer a client-relevant set of AVX-512 instructions. Meanwhile, AMD introduced AVX-512 support with "Zen 4," and would go on to improve AVX-512 performance with "Zen 5." The reentry of AVX-512 on Core could advance client AI inferencing applications.
