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.
