The AMD Opteron 2222 was a server/workstation processor with 2 cores, launched in August 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 2222 CPUs can link up in a multi-processor (SMP) configuration. Opteron 2222 has 1 MB of L2 cache per core and operates at 3 GHz. AMD is building the Opteron 2222 on a 90 nm production process using 227 million transistors. The multiplier is locked on Opteron 2222, which limits its overclocking capabilities.
With a TDP of 95 W, the Opteron 2222 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 2222 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 2222, which greatly improves virtual machine performance.
