Rocket LakeisIntel'scodenamefor its 11th generationCoremicroprocessors.Released on March 30, 2021,[2]it is based on the newCypress Covemicroarchitecture, a variant ofSunny Cove(used by Intel'sIce Lakemobile processors) backported to Intel's 14 nmprocess node.[4]Rocket Lake cores contain significantly moretransistorsthanSkylake-derivedComet Lakecores.
Rocket Lake features the sameLGA 1200socket and 400-series chipset compatibility asComet Lake,except H410 and B460 chipsets. It is accompanied by new 500-series chipsets as well.[5]Rocket Lake has up to eight cores, down from 10 cores for Comet Lake. It featuresIntel Xegraphics, and PCIe 4.0 support.[6]Only a singleM.2drive is supported in PCIe 4.0 mode, while all the rest are wired via PCIe 3.0.[7]
Intel officially launched the Rocket Lake desktop family on March 16, 2021, with sales commencing on March 30.[8]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.[9]Intel also releasedTiger Lakeprocessors as part of the 11th generation lineup in the desktop/NUCand tablet market. Such processors have the new B suffix in the model names.
