Intel Nova Lake officially confirmed with AVX-512 on both P-cores and E-cores

Intel officially confirmed in its 60th Architecture Instruction Set Extensions and Future Features manual that Core Ultra Series 4 "Nova Lake" processors will support AVX10.2 and AVX-512 across both performance cores (Coyote Cove) and efficiency cores (Arctic Wolf). AVX-512 is a 512-bit SIMD instruction set that accelerates vectorized workloads in AI, scientific computing, encoding, and simulation—capabilities absent from Intel's consumer line since 11th-gen Rocket Lake (2021).

Linux kernel patches released July 7 confirm the implementation, showing AVX10.2 support on all core types, enabling unified memory operations across the hybrid architecture. The patch includes optimized RAID code paths showing 26-43% speedup over baseline AVX on AMD Zen 5. Nova Lake is expected to launch in late 2026 as a 52-core design with up to 288 MB cache, restoring Intel parity with AMD's Zen 5 architecture, which also implements full 512-bit vectorization.

For architects: AVX-512's return matters for AI workloads sensitive to vectorization—local inference models, matrix operations, and tensor libraries benefit materially. The dual-core implementation (no performance cliff when moving threads between P and E cores) removes the fragmentation that forced Intel to disable AVX-512 on hybrid Alder Lake and Raptor Lake. If supply-chain momentum holds, Nova Lake closes a three-generation gap and becomes the first Intel hybrid CPU to compete with AMD on vector acceleration at any core count.
