The Intel Xeon X3353 was a server/workstation processor with 4 cores, launched in August 2007. It is part of the Xeon lineup, using the Yorkfield architecture with Socket 771. Xeon X3353 has 6 MB of L2 cache and operates at 2.67 GHz. Intel is building the Xeon X3353 on a 45 nm production process using 820 million transistors. The multiplier is locked on Xeon X3353, which limits its overclocking capabilities. With a TDP of 80 W, the Xeon X3353 is relatively power-efficient compared to other server processors of its time. Intel's processor supports DDR2 and DDR3 memory with a dual-channel interface. ECC memory is supported, too, which is an important capability for mission-critical systems, to avoid data corruption. Actual memory technology support depends on the chosen motherboard, because the memory controller is located on the motherboard (not in the processor). For communication with other components in the system, Xeon X3353 uses a PCI-Express N/A connection. This processor lacks integrated graphics, you might need a graphics card. Hardware virtualization is available on the Xeon X3353, which greatly improves virtual machine performance.
