latest version of Intel's Architecture Instruction Set Extensions and Future Features Programming reference document offers some details about AMX, a new matrix processing extension that can be used to speed up certain tasks, including machine learning.
Intel describes it as the following: "Intel Advanced Matrix Extensions (Intel AMX) is a new 64-bit programming paradigm consisting of two components: a set of 2-dimensional registers (tiles) representing sub-arrays from a larger 2-dimensional memory image, and an accelerator able to operate on tiles, the first implementation is called TMUL (tile matrix multiply unit)."
AMX will be supported by the "Sapphire Rapids" Xeon CPUs, which are scheduled for a 2021 release.
