The Intel Core i5-11600K is a desktop processor with 6 cores launched in March 2021. It is part of the Core i5 lineup using the Rocket Lake-S architecture with Socket 1200. Thanks to Intel Hyper-Threading the core-count is effectively doubled to 12 threads. Core i5-11600K has 12MB of L3 cache and operates at 3.9 GHz by default but can boost up to 4.9 GHz depending on the workload. Intel is making the Core i5-11600K on a 14 nm production node the transistor count is unknown. You may freely adjust the unlocked multiplier on Core i5-11600K which simplifies overclocking greatly as you can easily dial in any overclocking frequency. With a TDP of 125 W the Core i5-11600K consumes a lot of power so good cooling is definitely needed. Intel's processor supports DDR4 memory with a dual-channel interface. The highest officially supported memory speed is 3200 MHz but with overclocking (and the right memory modules) you can go even higher. For communication with other components in the computer Core i5-11600K uses a PCI-Express Gen 4 connection. This processor features the UHD Graphics 750 integrated graphics solution. Hardware virtualization is available on the Core i5-11600K which greatly improves virtual machine performance. Additionally IOMMU virtualization (PCI passthrough) is supported so that guest virtual machines may directly use host hardware. Programs using Advanced Vector Extensions (AVX) can run on this processor boosting performance for calculation-heavy applications. Besides AVX Intel has added support for the newer AVX2 and AVX-512 instructions too.
