The AMD Opteron 2220 was a server/workstation processor with 2 cores, launched in February 2007, at an MSRP of $698. It is part of the Opteron lineup, using the Santa Rosa architecture with Socket F. To further increase overall system performance, up to two Opteron 2220 CPUs can work together in a multi-processor (SMP) configuration. Opteron 2220 has 1 MB of L2 cache per core and operates at 2.8 GHz. AMD is making the Opteron 2220 on a 90 nm production node using 227 million transistors. The multiplier is locked on Opteron 2220, which limits its overclocking potential.
With a TDP of 95 W, the Opteron 2220 consumes a good deal of power, so decent cooling is needed. AMD's processor supports DDR2 memory with a dual-channel interface. The highest officially supported memory speed is 667 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 computer, Opteron 2220 uses a PCI-Express Gen 1 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. Hardware virtualization is available on the Opteron 2220, which greatly improves virtual machine performance.
