Comet Lake

For the lake, see Comet Lake (Ohio).

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]

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;^[13] 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

1. Transistorized memory, such as RAM, ROM, flash and cache sizes as well as file sizes are specified using binary meanings for K (1024¹), M (1024²), G (1024³), etc.
2. Price is Recommended Customer Price (RCP) at launch. RCP is the trade price that processors are sold by Intel to retailers and OEMs. Actual MSRP for consumers is higher

List of 10th generation Comet Lake Refresh processors

Desktop processors

On March 16, 2021, Intel announced the refreshed models of Comet Lake Core i3 and Pentium Gold processors. These processors have the same characteristics as their original parts, albeit with a 100MHz higher frequency and the last digit changing from zero to five.^[19]
