Product Description
Intel Core i5-11600K is the most affordable unlocked (K-series) desktop microprocessor in Intel's 11th-gen Core, Rocket Lake family. It is also available without integrated graphics in the form of i5-11600KF.
Like its predecessor, the Core i5-11600K comes with 6 cores and 12 threads, though it is clocked marginally higher.
Rocket Lake is based on its new Cypress Cove microarchitecture backported to the 14nm process. Intel claims significant IPC (instructions per clock) increase, though reviewers have mixed feedbacks on observed performance.
Another area where Intel improved is the integrated graphics, now named Intel UHD 750. It is the same unit found in higher-powered Rocket Lake processors.
Last but not least, the new Rocket Lake processors support DDR4-3200MHz memories, though the i5-11600K/KF defaults to 2:1 ratio of DRAM to memory controller at this frequency. Intel also includes PCIe 4.0 support with up to 20 lanes.
Alongside the i5-11600K, Intel also markets the Core i5-11600KF. The "F" designation means the i5-11600KF does not come with the integrated graphics.
Three other i5 CPUs in the 11th-gen include the i5-11600, i5-11500, and i5-11400 as well as their derivatives.
