Comet Lake
Edit
The content is sourced from: https://handwiki.org/wiki/Engineering:Comet_Lake

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, 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. Intel officially launched Comet Lake-Refresh CPUs on the same day as 11th Gen Core Rocket Lake launch. The low-power mobile Comet Lake-U Core and Celeron 5205U CPUs were discontinued on July 7, 2021.

1. 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.[1]

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;[2] 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.[3][4][5][6]

Entry-level CPUs like the i3 series no longer support ECC memory.[7]

2. List of 10th Generation Comet Lake Processors
