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:

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]
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.
