Cooper Lake (CPL / CPX) is Intel's successor to Cascade Lake, a 14 nm microarchitecture for the multiprocessing server market only.

Launched in mid-2020, Cooper Lake covers the 4-way and 8-way multiprocessing segments while Ice Lake serves the single and dual-socket segments.

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

Codenames

Single and dual-socket Cooper Lake parts were scrapped before ever making it to market.
