Overview

AI Compute Extensions (ACE) is a major update to the x86 instruction set architecture introduced in 2026. It shifts the fundamental calculation method from dot products (inner products) to outer products, enabling a 16x increase in matrix multiplication density. It introduces dedicated tile registers and native support for low-precision formats like OCP MX to compete with dedicated NPUs and GPUs.
