The Intel Xeon W3670 was a server/workstation processor with 6 cores, launched in August 2010. It is part of the Xeon lineup, using the Gulftown architecture with Socket 1366. Thanks to Intel Hyper-Threading the core-count is effectively doubled, to 12 threads. Xeon W3670 has 12 MB of L3 cache and operates at 3.2 GHz by default, but can boost up to 3.466 GHz, depending on the workload. Intel is building the Xeon W3670 on a 32 nm production process using 1,170 million transistors. The multiplier is locked on Xeon W3670, which limits its overclocking capabilities.
With a TDP of 130 W, the Xeon W3670 consumes a lot of power, so good cooling is definitely needed. Intel's processor supports DDR3 memory with a triple-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 computer, Xeon W3670 uses a PCI-Express Gen 2 connection. This processor lacks integrated graphics, you might need a graphics card.
Hardware virtualization is available on the Xeon W3670, which greatly improves virtual machine performance.
