Intel Core i9-11900K specifications are filtered: up to 5.3 GHz, PCIe 4.0 support and up to 250W power

A leaker shared the filtered specifications of the Core i9-11900k, Intel’s 11th generation CPU, codenamed Rocket Lake-S, on Twitter. The new line is expected to launch in 2021 and will feature the new Cypress Cove cores.

User feedback suggests Intel’s flagship processor, the i9-11900K, will reach a single-core turbo frequency of 5.3 GHz, while all cores will run at 4.80 GHz.

In comparison, the 10th generation i9-10900K has a 100 MHz lower frequency on all cores, while the single-core frequency is the same. The exception is that the current processor offers 2 more cores than Intel’s next CPU flagship with 10 cores and 20 threads.

In terms of power consumption, user davidbepo noted that the i9-11900K will have a maximum PL1 (Power Level 1) of 125W and a PL2 of 250W.


The only mistake is in the maximum frequency of all cores, which should be 4.6 GHz instead of 4.7 GHz for the i5 11600K.

Other rumors say that Thermal Velocity Boost should only be available for the Core i9 series, while only the Core i7 should be compatible with Turbo Boost Max 3.0. Therefore, the described frequencies should not be considered as the only type of boost.

The new CPU series, although based on 14 nm, will be the first Intel architecture other than Skylake (from 2015). It will also be the first from Intel to support PCI Express 4.0 on all major platforms and offer integrated Xe graphics.

The 11th generation will be compatible with existing LGA1200 motherboards. The company is also working with its partners to launch 500-series motherboards early next year.
