The Intel Core i7-875K was a desktop processor with 4 cores, launched in May 2010, at an MSRP of $353. It is part of the Core i7 lineup, using the Lynnfield architecture with Socket 1156. Thanks to Intel Hyper-Threading the core-count is effectively doubled, to 8 threads. Core i7-875K has 8 MB of L3 cache and operates at 2.933 GHz by default, but can boost up to 3.6 GHz, depending on the workload. Intel is making the Core i7-875K on a 45 nm production node using 774 million transistors. You may freely adjust the unlocked multiplier on Core i7-875K, which simplifies overclocking greatly, as you can easily dial in any overclocking frequency.
With a TDP of 95 W, the Core i7-875K consumes a good deal of power, so decent cooling is needed. Intel's processor supports DDR3 memory with a dual-channel interface. The highest officially supported memory speed is 1333 MT/s, but with overclocking (and the right memory modules) you can go even higher. For communication with other components in the system, Core i7-875K uses a PCI-Express Gen 2 connection. This processor does not have integrated graphics, you will need a separate graphics card.
Hardware virtualization is available on the Core i7-875K, which greatly improves virtual machine performance. Additionally, IOMMU virtualization (PCI passthrough) is supported, so that guest virtual machines may directly use host hardware.
