The Intel Core i7-870 was a desktop processor with 4 cores, launched in September 2009. 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 i7-870 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 building the Core i7-870 on a 45 nm production process using 774 million transistors. The multiplier is locked on Core i7-870, which limits its overclocking capabilities. With a TDP of 95 W, the Core i7-870 consumes a good deal of power, so decent cooling is needed. Intel's processor supports DDR3 memory with a dual-channel interface. For communication with other components in the machine, Core i7-870 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 i7-870, which greatly improves virtual machine performance.
