Rocket Lake
Rocket Lake is Intel's codename for its 11th generation Core microprocessors. Released on March 30, 2021,[2] it is based on the new Cypress Cove microarchitecture, a variant of Sunny Cove (used by Intel's Ice Lake mobile processors) backported to Intel's 14 nm process node.[3] Rocket Lake cores contain significantly more transistors than current Skylake-derived Comet Lake cores.

Rocket Lake features the same LGA 1200 socket and 400-series chipset compatibility as Comet Lake, except H410 and B460 chipsets. It is accompanied by new 500-series chipsets as well.[4] Rocket Lake has up to eight cores, down from 10 cores for Comet Lake. It features Intel Xe graphics, and PCIe 4.0 support.[5] Only a single M.2 drive is supported in PCI-E 4.0 mode, all the rest are wired via PCI-E 3.0.[6]
Intel officially launched the Rocket Lake desktop family on March 16, 2021 with sales commencing on March 30.[7] The 11th generation Core i3, as well as Rocket Lake-based Pentium Gold and Celeron CPUs were not included along with the higher-end models; instead, Intel launched refreshed models for Comet Lake Core i3 and Pentium Gold CPUs. These processors have the same characteristics as their original parts, albeit with a 100MHz higher frequency and the last digit of their model numbers changing from zero to five.[8] Intel also released Tiger Lake processors as part of the 11th generation lineup in the desktop/NUC and tablet market. Such processors have the new B suffix in the model names.
