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]
