The Intel Xeon W3680 was a server/workstation processor with 6 cores, launched in March 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 W3680 has 12 MB of L3 cache and operates at 3.333 GHz by default, but can boost up to 3.6 GHz, depending on the workload. Intel is making the Xeon W3680 on a 32 nm production node using 1,170 million transistors. You may freely adjust the unlocked multiplier on Xeon W3680, which simplifies overclocking greatly, as you can easily dial in any overclocking frequency.
With a TDP of 130 W, the Xeon W3680 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 system, Xeon W3680 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 W3680, which greatly improves virtual machine performance.
