The Intel Xeon MP 7040 Dual-Core was a server/workstation processor with 2 cores, launched in December 2005. It is part of the Xeon MP lineup, using the Paxville MP architecture with Socket 604. To further increase overall system performance, up to two Xeon MP 7040 Dual-Core CPUs can link up in a multi-processor (SMP) configuration. Xeon MP 7040 Dual-Core has 1 MB of L2 cache and operates at 3 GHz. Intel is building the Xeon MP 7040 Dual-Core on a 90 nm production process using 200 million transistors. The multiplier is locked on Xeon MP 7040 Dual-Core, which limits its overclocking capabilities.
With a TDP of 135 W, the Xeon MP 7040 Dual-Core consumes a lot of power, so good cooling is definitely needed. 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 MP 7040 Dual-Core uses a PCI-Express N/A connection. This processor lacks integrated graphics, you might need a graphics card.
The SSE4 instruction set is not supported, which can cause problems with modern games, as they require that capability.
