Intel Core i9-11900KF Processor

8C/16T · 5.3 GHz · 125 W

The Intel Core i9-11900KF is the graphics-free version of the Core i9-11900K, flagship of the 11th Gen Rocket Lake desktop family. Rocket Lake backported the newer Cypress Cove core design to Intel's 14 nm process, bringing AVX-512 and PCIe 4.0 to the LGA 1200 platform while reducing the top core count to eight. The KF model needs a discrete graphics card and supports Thermal Velocity Boost.
