If you are waiting on news of Intel's upcoming Rocket Lake processors then I have something for you today. One of our sources provided us with the complete technical specifications of Intel's upcoming Core i9 and Core i7 Rocket Lake family. Intel's Rocket Lake architecture represents the first significant architectural upgrade in over 6 years and will feature PCIe 4.0. It will finally allow Intel to achieve parity with AMD's PCIe 4.0 equipped Zen platform as well as a massive IPC boost over Skylake.

Before I begin, keep in mind that the B-0 stepping is essentially the QS sample and while this revision is usually final, Intel may decide to polish these some more. In that case, the final variant could potentially be better than this - but not worse. The company's flagship Rocket Lake CPU, the Core i9 11900K will be able to boost to an astounding 5.3GHz single-core and 4.8GHz all-core thanks to Intel's incredibly mature 14nm process.
