Comet Lake is Intel's codename for its 10th generation Core processors. They are manufactured using Intel's third 14 nm Skylake process revision, succeeding the Whiskey Lake U-series mobile processor and Coffee Lake desktop processor families. Intel announced low-power mobile Comet Lake-U CPUs on August 21, 2019,[5] H-series mobile CPUs on April 2, 2020,[6] desktop Comet Lake-S CPUs April 30, 2020,[7] and Xeon W-1200 series workstation CPUs on May 13, 2020.[8] Comet Lake processors and Ice Lake 10 nm processors are together branded as the Intel "10th Generation Core" family.[9] In March 2021, Intel officially launched Comet Lake-Refresh Core i3 and Pentium CPUs on the same day as the 11th Gen Core Rocket Lake launch.[10] The low-power mobile Comet Lake-U Core and Celeron 5205U CPUs were discontinued on July 7, 2021.[11]
