Intel released a product change notification (PCN) earlier this week, announcing the discontinuation of its "Cascade Lake-X" and "Cascade Lake-W" HEDT processors. This effectively marks the end for the LGA2066 HEDT platform, as well as the Xeon W-2200 series workstation processors. The final iteration of the "Skylake" CPU core, "Cascade Lake" introduced features such as AVX512, VNNI, GFNI, and DLBoost, forming Intel's first attempt at providing hardware acceleration for AI neural-net building/training. The company plans a more comprehensive hardware accelerator with "Meteor Lake," called AI Boost.
