Intel Nova Lake-S Tested With AVX-512 and APX Enabled

Posted on
Leaked Nova Lake-S testing shows AVX-512 and APX enabled on desktop parts, signaling a return of advanced vector instructions to client CPUs.

Quick Report

Intel's next desktop CPU generation appears to be testing with AVX-512 and APX enabled, giving fresh evidence that the company is bringing advanced vector instruction support back to client hardware. A leaked test identified 24-core and 28-core Nova Lake-S samples operating with AVX-512 and APX support, which would align the desktop roadmap more closely with Intel's HEDT and Xeon ecosystem.

The move would reverse the earlier client-side decision to disable AVX-512 on Alder Lake and Raptor Lake, where the feature was mostly reserved for datacenter or workstation platforms. With the Coyote Cove P-cores and Arctic Wolf E-cores carrying the new instructions, Nova Lake-S could provide stronger compute performance for scientific workloads, signal processing, and vector heavy software, while also making the desktop product line feel more aligned with Intel's broader architecture strategy.
