More evidence for AVX10 and APX support in Intel Nova Lake

Assembler updates and recent compiler patches present conflicting signals about AVX10, APX and AMX support on Intel Nova Lake, which could bring 512-bit acceleration and Artificial Intelligence-focused matrix instructions to consumer chips.

Intel instruction set extensions AVX10, APX and AMX are designed to enable 512-bit acceleration and fast vector and matrix multiplication for tasks such as content creation, encoding and decoding, and Artificial Intelligence. Recent activity in the Netwide Assembler project has suggested that these extensions may appear in the consumer Nova Lake lineup, reviving the possibility that advanced x86 features might not remain exclusive to Xeon server parts.

That optimism contrasts with a recent GCC compiler patch that indicated the initial Nova Lake enablement does not include AVX10, AMX or APX. A few weeks earlier reporting had likewise suggested Nova Lake would arrive without Intel’s newer x86 extensions. The article notes that NASM released version 3.0 and then a 3.1 update, and those assembler changes are the basis for renewed expectations that 512-bit acceleration support could return to client CPUs with Nova Lake.

Historical context in the piece highlights Intel’s choice to disable AVX-512 in the Alder Lake and Raptor Lake client lineups, limiting 512-bit data paths to Xeon servers. Nova Lake is rumored to feature up to 52 cores, described as 16 performance cores, 32 efficient cores and 4 low-power engine cores. The article frames Nova Lake as potentially well suited to gaming and workstation workloads while server applications would remain targeted at Xeon. It also emphasizes that consumer support for AVX-class instructions could allow Nova Lake to leverage the existing ecosystem of AVX-accelerated software.
