Cascade Lake is an Intel codename for a 14 nm server, workstation and enthusiast processor generation, launched in April 2019. In Intel's process–architecture–optimization model, Cascade Lake is an optimization of Skylake. Intel states that this will be their first generation to support 3D XPoint-based memory modules. It also features Deep Learning Boost (DPL) instructions and mitigations for Meltdown and Spectre. Intel officially launched new Xeon Scalable SKUs on February 24, 2020.
