Additional information

Comet Lake

Intel processor microarchitecture

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, H-series mobile CPUs on April 2, 2020, desktop Comet Lake-S CPUs April 30, 2020, and Xeon W-1200 series workstation CPUs on May 13, 2020. Comet Lake processors and Ice Lake 10 nm processors are together branded as the Intel "10th Generation Core" family. 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. The low-power mobile Comet Lake-U Core and Celeron 5205U CPUs were discontinued on July 7, 2021.

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.⁸

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;⁹ Turbo Boost Max 3.0 support for Core i7 and 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.¹⁰ ¹¹ ¹² ¹³

Entry-level CPUs like the i3 series no longer support ECC memory.¹⁴
