Intel · Core i5 · 2021 · LGA1200
The Intel Core i5-11600K is a desktop processor with 6 cores, released in 2021 at an MSRP of $262. It is part of the Core i5 lineup, using the 11th Gen platform, and fits the LGA1200 socket. Internally, it is built on the "Rocket Lake" architecture. Thanks to Intel Hyper-Threading, each core can handle two instruction streams simultaneously, yielding a total of 12 threads for improved parallelism. The Core i5-11600K has a base clock of 3.9 GHz and can boost up to 4.9 GHz depending on workload and thermal headroom. Intel manufactures the "Rocket Lake" silicon on a 14nm process node. The multiplier is unlocked, making overclocking straightforward. This processor supports DDR4 memory. With a TDP of 125W, the Core i5-11600K sits in a typical power envelope for a modern desktop CPU. Integrated graphics are provided by the UHD 750 solution, so a discrete GPU is not required for display output. The cache hierarchy consists of 64KB/core of L1, 3MB of L2, and 12MB of L3 cache.
Rocket Lake's mainstream enthusiast chip, offering 6 cores and 12 threads with an unlocked multiplier for overclocking. Competed directly against AMD's Ryzen 5 5600X, with Intel generally holding a gaming performance edge and AMD offering better power efficiency.
