Comet Lake

Comet Lake is Intel's codename for the fourth 14 nm Skylake process-refinement, following Whiskey Lake for U-series mobile processors and Coffee Lake for others. Intel announced low power mobile Comet Lake-U CPUs availability on August 21, 2019.[2] Intel announced 10th generation Intel Core H-series mobile SoCs on April 2, 2020.[3] Desktop Comet Lake-S CPUs were announced on April 30, 2020.[4] Intel announced Xeon W-1200 series workstation CPUs on May 13, 2020.[5]

Not to be confused with Comet Lake (Ohio).
