Rocket Lake
Rocket Lake is a codename for Intel’s desktop x86 chip family which is to be released in the first quarter of 2021. It will be based on the new Cypress Cove microarchitecture, a variant of Sunny Cove (used by Intel's Ice Lake mobile processors) backported to the older 14nm process.[1] The chips will be marketed as "Intel 11th generation Core". The Rocket Lake cores contain significantly more transistors than current Skylake-derived Comet Lake cores.

Rocket Lake will feature the same LGA 1200 socket and 400-series chipset compatibility as Comet Lake, excepted H410 and B460 chipsets. It will be accompanied by a new 500-series chipset as well.[2] Rocket Lake will have up to 8 cores, down from 10 cores for Comet Lake. It will feature Intel Xe graphics, and PCIe 4.0 support.[3]
