Intel previewed its upcoming Rocket Lake architecture for the first time at CES 2021. The upcoming Rocket Lake CPUs mark the first really big architectural overhaul in well over 5 years and is also an architecture that, due to circumstances, has been backported from 10nm at great expense so that Intel can get it to market as quickly as possible. It will also finally bring the long-awaited PCIe 4.0 support to Intel’s mainstream platform, something that has been sorely lacking until now.
