Intel and AMD Publish Ace AI Extension Spec for X86 Chips
The ACE specification gives Intel and AMD a shared, standardized path to speed up AI inference on x86 hardware, reducing reliance on separate accelerators.
Reporting from 1 sources: GIGAZINE.
The x86 Ecosystem Advisory Group, led by Intel and AMD, published the specification for AI Compute Extensions (ACE) on June 15, 2026. ACE is a set of extension instructions for x86 CPUs designed to accelerate matrix operations during AI inference. It supports INT8, BF16, MXFP8, and MXINT8 precision natively. Work on compilers, debuggers, and profilers is underway, with integration into PyTorch and TensorFlow planned.
The x86 Ecosystem Advisory Group published the AI Compute Extensions (ACE) specification on June 15, 2026. ACE is an extension instruction set for x86 CPUs that handles matrix operations in two dimensions rather than one, which the group says speeds up AI inference. The spec natively supports INT8, BF16, MXFP8, and MXINT8 precision. Toolchain development for compilers, debuggers, and profilers is already in progress, and integration into machine learning frameworks PyTorch and TensorFlow is planned. The advisory group includes Intel, AMD, Broadcom, Dell, Google, Hewlett Packard Enterprise, HP, Lenovo, Meta, Microsoft, Oracle, and Red Hat.
