Coffee Lake

Cooper Lake (CPL) is Intel's successor to Cascade Lake, a 14 nm microarchitecture for enthusiasts and servers. Though announced to be releasing in 1H2020 for all segments, Intel said that, in an effort to streamline their product portfolio, the mainstream version (based on the Whitley) is going to be scrapped and just the Cedar Island chips are going to be released. These are chips that range from 28 to 56 cores, primarily targeted at niche AI and HPC workloads, hence the bfloat16 (brain floating-point format) support.

For scalable server class processors, Intel branded it as Xeon Bronze, Xeon Silver, Xeon Gold, and Xeon Platinum.
