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.[4] 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.[5] Rocket Lake has up to eight cores, down from 10 cores for Comet Lake. It features Intel Xe graphics, and PCIe 4.0 support.[6] Only a single M.2 drive 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 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.

Features

List of 11th generation Rocket Lake processors

Rocket Lake-S (Desktop processors)

  • All CPUs listed below support DDR4-3200 natively. The Core i9 K/KF processors support a 1:1 ratio of DRAM to memory controller by specification at DDR4-3200, whereas the Core i9 non K/KF and all other CPUs listed below support a 2:1 ratio of DRAM to memory controller at DDR4-3200 and a 1:1 ratio at DDR4-2933.[29]
  • All CPUs support up to 128 GB of RAM in dual channel mode[30]
  • Core i9 CPUs (except 11900T) support Intel Thermal Velocity Boost technology[31][32]
