Comet Lake is Intel's codename for its 10th generation Core microprocessors. They are manufactured using Intel's third 14 nm Skylake process refinement, 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,^[2] H-series mobile CPUs on April 2, 2020,^[3] desktop Comet Lake-S CPUs April 30, 2020,^[4] and Xeon W-1200 series workstation CPUs on May 13, 2020.^[5] Comet Lake processors and Ice Lake 10 nm processors are together branded as the Intel "10th Generation Core" family.^[6] Intel officially launched Comet Lake-Refresh CPUs on the same day as 11th Gen Core Rocket Lake launch.^[7] The low-power mobile Comet Lake-U Core and Celeron 5205U CPUs were discontinued on July 7, 2021.^[8]

Generational changes

All Comet Lake CPUs feature an updated Platform Controller Hub with CNVio2 controller with Wi-Fi 6 and external AX201 CRF module support.^[9]

Comet Lake-S compared to Coffee Lake-S Refresh

Up to ten CPU cores
Hyperthreading on all models, except for Celeron
Single core turbo boost up to 5.3 GHz (300 MHz higher); all-core turbo boost up to 4.9 GHz; Thermal Velocity Boost for Core i9;^[10] Turbo Boost Max 3.0 support for Core i7, i9
DDR4-2933 memory support for Core i7 and i9; DDR4-2666 for Core i3, Core i5, Pentium Gold, Celeron
400-series chipset based on the LGA 1200 socket

Comet Lake-H compared to Coffee Lake-H Refresh

Higher turbo frequencies by up to 300 Mhz
DDR4-2933 memory support
Thermal Velocity Boost for Core i7 and i9

Comet Lake-U compared to Whiskey Lake-U

Up to six CPU cores
Higher turbo frequencies by up to 300 MHz
DDR4-2666 and LPDDR3-2133 memory support

One notable architectural change of Comet Lake from its predecessors is removal of TSX instruction set extensions.^[11]^[12]^[13]^[14]

Entry-level CPUs like the i3 series no longer support ECC memory.^[15]

List of 10th generation Comet Lake processors

Desktop processors

The i9-10900K and 10900KF support Thermal Velocity Boost up to 5.3 GHz. The i9-10900, i9-10900F and i9-10850K support Thermal Velocity Boost up to 5.2 GHz.
