The Intel Core i5-6600K was a desktop processor with 4 cores, launched in August 2015, at an MSRP of $242. It is part of the Core i5 lineup, using the Skylake architecture with Socket 1151. Core i5-6600K has 6 MB of L3 cache and operates at 3.5 GHz by default, but can boost up to 3.9 GHz, depending on the workload. Intel is making the Core i5-6600K on a 14 nm production node, the transistor count is unknown. You may freely adjust the unlocked multiplier on Core i5-6600K, which simplifies overclocking greatly, as you can easily dial in any overclocking frequency.
With a TDP of 91 W, the Core i5-6600K consumes a good deal of power, so decent cooling is needed. Intel's processor supports DDR3 and DDR4 memory with a dual-channel interface. The highest officially supported memory speed is 2133 MT/s, but with overclocking (and the right memory modules) you can go even higher. For communication with other components in the machine, Core i5-6600K uses a PCI-Express Gen 3 connection. This processor features the HD Graphics 530 integrated graphics solution.
Hardware virtualization is available on the Core i5-6600K, which greatly improves virtual machine performance. Programs using Advanced Vector Extensions (AVX) can run on this processor, boosting performance for calculation-heavy applications. Besides AVX, Intel is including the newer AVX2 standard, too, but not AVX-512.
