The Intel Xeon E5-2637 v2 is a server/workstation processor with 4 cores, launched in September 2013. It is part of the Xeon E5 lineup, using the Ivy Bridge-EP architecture with Socket 2011. Thanks to Intel Hyper-Threading the core-count is effectively doubled, to 8 threads. To further increase overall system performance, up to two Xeon E5-2637 v2 CPUs can link up in a multi-processor (SMP) configuration. Xeon E5-2637 v2 has 10 MB of L3 cache and operates at 3.5 GHz. Intel is building the Xeon E5-2637 v2 on a 22 nm production process using 1,400 million transistors. The multiplier is locked on Xeon E5-2637 v2, which limits its overclocking capabilities.

With a TDP of 130 W, the Xeon E5-2637 v2 consumes a lot of power, so good cooling is definitely needed. Intel's processor supports DDR3 memory with a quad-channel interface. ECC memory is supported, too, which is an important capability for mission-critical systems, to avoid data corruption. For communication with other components in the machine, Xeon E5-2637 v2 uses a PCI-Express Gen 3 connection. This processor lacks integrated graphics, you might need a graphics card.
Hardware virtualization is available on the Xeon E5-2637 v2, which greatly improves virtual machine performance. Additionally, IOMMU virtualization (PCI passthrough) is supported, so that guest virtual machines may directly use host hardware. Programs using Advanced Vector Extensions (AVX) will run on this processor, boosting performance for calculation-heavy applications.
