According to Twitter user davidbepo (@davidbepo), the 11900K is rumoured to have ship out with a boost clock of 5.3GHz via Intel’s Thermal Velocity Boost (TVB) technology, but only for single-core performance. With all cores running, though, that frequency is reduced to 4.8GHz. Moreover and as mentioned in earlier reports, the CPU is expected to run on an 8-cores, 16-threads layout. Instead of a 10-cores, 20-threads layout like its predecessor, the Core i9-10900K. Additionally, Rocket Lake-S CPUs are expected to support PCIe 4.0, nearly a year after its rival, AMD, introduced the interface to the world with the launch of its Ryzen 3000 series CPUs. Sadly, the CPU lineup will still ship out on the already archaic 14nm die lithography, although it is based on Intel’s new Cypress Cove microarchitecture and backported from the 10nm Sunny Cove architecture.
— davidbepo (5 GHz overload) (@davidbepo) December 11, 2020 To that end, Intel has also said that the new Rocket Lake-S CPUs will be backwards compatible with its current 400 series LGA1200 motherboards, although it is working closely with its board partners to also launch its new 500 series motherboards alongside the new CPU line. Having said that, the specifications mentioned here are still just hearsay, therefore we recommend that you take this news with a pinch of salt until Intel releases some more tangible news.
