Intel · Core i7 · 2014 · LGA2011-3
The Intel Core i7-5820K is a desktop processor with 6 cores, released in 2014 at an MSRP of $389. It is part of the Core i7 lineup, using the 5th Gen platform, and fits the LGA2011-3 socket. Internally, it is built on the "Haswell-E" 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 i7-5820K has a base clock of 3.3 GHz and can boost up to 3.6 GHz depending on workload and thermal headroom. Intel manufactures the "Haswell-E" silicon on a 22nm process node. The multiplier is unlocked, making overclocking straightforward. This processor supports DDR4 memory. With a TDP of 140W, the Core i7-5820K sits in a typical power envelope for a modern desktop CPU. This processor has no integrated graphics — a discrete GPU is required. The cache hierarchy consists of 32KB/core of L1, 256KB/core of L2, and 15MB of L3 cache.
