The Intel Core i7-3970X Extreme is a desktop processor with 6 cores, released in 2012 at an MSRP of $1,059. It is part of the Core i7 lineup, using the Sandy Bridge-E platform, and fits the LGA2011 socket. Internally, it is built on the "Sandy Bridge-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 i7-3970X Extreme has a base clock of 3.5 GHz and can boost up to 4 GHz depending on workload and thermal headroom. Intel manufactures the "Sandy Bridge-E" silicon on a 32nm process node. The multiplier is unlocked, making overclocking straightforward. This processor supports DDR3 memory. With a TDP of 150W, the Core i7-3970X Extreme runs hot and requires a capable cooling setup. 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.
Refresh of the 3960X — higher clocks and 150W TDP. Still 6 cores despite the $1,059 Extreme Edition pricing.
