Rocket Lake (RKL) is a microarchitecture designed by Intel as a successor to Comet Lake for desktops and single-socket servers.


Codenames[edit]

Core Description Graphics Target
Rocket Lake S Mainstream performance GT2 Desktop performance to value, AiOs, and minis
Rocket Lake U Ultra-low power GT2 Light notebooks, portable All-in-Ones (AiOs), Minis, and conference room

Brands[edit]

Intel has released Rocket Lake under the following brand families:

Logo Family General Description Differentiating Features
Cores HT AVX AVX2 AVX512 TVB ECC

core i9 logo (2020).png Core i9 High-end Performance Octa ✔ ✔ ✔ ✔ ✔ ✘
50px Xeon 1S Server & Workstation 4-8 ✔ ✔ ✔ ✔ ✘ ✔

Release Dates[edit]

Rocket Lake was officially introduced on March 16, 2021 and went on sale from March 30, 2021. Limited quantities of the Core i7-11700K were (accidentally?) available through the German reseller Mindfactory on March 6, 2021.

The Xeon W-1300 Line using Rocket Lake is expected to be officially launched in Q3/2021.

Compatibility[edit]

New text document.svg This section is empty; you can help add the missing info by editing this page.

Rocket Lake will feature the same LGA1200 socket as Comet Lake. Rocket Lake is backwards compatible with Comet Lake. Rocket Lake will have new motherboards and a new 500 series chipset. Rocket Lake will not be compatible with Alder Lake.

Compiler support[edit]

Compiler Arch-Specific Arch-Favorable
ICC -march=? -mtune=?
GCC -march=rocketlake -mtune=rocketlake
LLVM -march=? -mtune=?
Visual Studio /arch:AVX512 /?
