The Intel Core i5-6600K is a desktop processor with 4 cores, launched in July 2015. It is part of the Core i5 lineup, using the Skylake architecture with Socket 1151. Core i5-6600K has 6MB 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 95 W, the Core i5-6600K consumes a good deal of power, so decent cooling is needed. Intel's processor supports DDR4 memory with a dual-channel interface. The highest officially supported memory speed is 2133 MHz, 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 does not have integrated graphics, you will need a separate graphics card.
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.
