Is x86 ready to ACE it?
Summary
A detailed guest post analyzing Intel ACE, its ACE accelerator alongside AMX TMUL, and Arm SME/SME2. It covers tile registers, outer-product vs inner-product computation, data type conversions, scaling, and tiling, with a comparison of bandwidth and cache implications across AMX, ACE, and SME. The piece argues that hardware implementation quality will largely determine ACE’s performance edge and discusses implications for future CPUs from Intel, AMD, and Arm.
