Rocket Lake is Intel's codename for its 11th-generation Core-branded microprocessors. Released on March 30, 2021, 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. Rocket Lake cores contain significantly more transistors than 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. Rocket Lake has up to eight cores, down from 10 cores for Comet Lake. It features Intel Xe graphics, and PCIe 4.0 support. Only a single M.2 drive is supported in PCIe 4.0 mode, while all the rest are wired via PCIe 3.0.
Intel officially launched the Rocket Lake desktop family on March 16, 2021, with sales commencing on March 30. 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 100 MHz higher frequency and the last digit of their model numbers changing from zero to five. 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.
