Anandtech published Intel Rocket Lake (14nm) Review: Core i9-11900K, Core i7-11700K, and Core i5-11600K A quote from the article:

Today is the official launch of Intel’s 11th Generation Core processor family, given the internal name ‘Rocket Lake’. Rocket Lake showcases new performance gains for Intel in the desktop space, with a raw clock-for-clock performance uplift in a number of key workloads. In order to do this, Intel have had to retrofit its 10nm CPU and GPU designs back to 14nm, because only 14nm can achieve the frequency required. In exchange, the new processors to get this performance run hot, cost more for Intel to produce, have two fewer cores at the high end, but customers also get PCIe 4.0 on Intel’s mainstream desktop platform for the first time. In our review today, we will be going over Intel’s new hardware, why it exists, and how it performs, focusing specifically on Intel’s new flagship, the Core i9-11900K, which has eight cores and can boost up to 5.3 GHz.
