Intel Drops 256-bit AVX-10 Mode, Goes All-in on 512-bit
2025-03-19
Intel has significantly revised its AVX-10 instruction set whitepaper, abandoning the previously planned optional 256-bit mode in favor of a full 512-bit vector width. This means future Intel E-core processors will fully support AVX-512, aligning with AMD's Zen 4 architecture. The change stems from updated GCC compiler patches removing 256-bit compatibility. This simplifies instruction set handling and boosts the competitiveness of future Intel Xeon E-core server platforms, better competing with AMD's EPYC processors. While a late decision, it positively impacts the future of the x86_64 microarchitecture.
