The Intel Xeon L3403 was a desktop processor with 2 cores, launched in October 2010. It is part of the Xeon lineup, using the Clarkdale architecture with Socket 1156. Xeon L3403 has 4 MB of L3 cache and operates at 2000 MHz. Intel is building the Xeon L3403 on a 32 nm production process using 382 million transistors. The multiplier is locked on Xeon L3403, which limits its overclocking capabilities.
With a TDP of 30 W, the Xeon L3403 consumes only little energy. Intel's processor supports DDR3 memory with a dual-channel interface. The highest officially supported memory speed is 1066 MT/s, but with overclocking (and the right memory modules) you can go even higher. 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 L3403 uses a PCI-Express Gen 2 connection. This processor features the Intel HD integrated graphics solution.
Hardware virtualization is available on the Xeon L3403, which greatly improves virtual machine performance. Additionally, IOMMU virtualization (PCI passthrough) is supported, so that guest virtual machines may directly use host hardware.
