Intel · Core i7 · 2013 · LGA2011
The Intel Core i7-4820K is a desktop processor with 4 cores, released in 2013 at an MSRP of $294. It is part of the Core i7 lineup, using the Ivy Bridge-E platform, and fits the LGA2011 socket. Internally, it is built on the "Ivy Bridge-E" architecture. Thanks to Intel Hyper-Threading, each core can handle two instruction streams simultaneously, yielding a total of 8 threads for improved parallelism. The Core i7-4820K has a base clock of 3.7 GHz and can boost up to 3.9 GHz depending on workload and thermal headroom. Intel manufactures the "Ivy Bridge-E" silicon on a 22nm process node. The multiplier is unlocked, making overclocking straightforward. This processor supports DDR3 memory. With a TDP of 130W, the Core i7-4820K 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 10MB of L3 cache.
Entry 4-core Ivy Bridge-E on LGA2011. Compatible with existing X79 Sandy Bridge-E motherboards.
