Intel has decided to reveal some additional details about its upcoming Rocket Lake processors and one of the major differences between leaks and reality is the fact that it actually features Cypress Cove cores - based on Ice Lake - instead of Willow Cove.

Intel's Rocket Lake processors will have up to 8 cores and feature 50% more integrated graphics power. RKL-S is based on the 14nm process, but unlike older generations, it will feature a revamped architecture based on the Sunny Cove (Ice Lake) architecture called Cypress Cove. It is essentially a backport of 10nm (non-SuperFin) to 14nm. PCIe 4.0 support and Xe 12 generation graphics have been added as well.
