The AMD Opteron X2 275 HE was a server/workstation processor with 2 cores, launched in February 2006. It is part of the Opteron X2 lineup, using the Italy architecture with Socket 940. To further increase overall system performance, up to two Opteron X2 275 HE CPUs can work together in a multi-processor (SMP) configuration. Opteron X2 275 HE has 1 MB of L2 cache and operates at 2.2 GHz. AMD is making the Opteron X2 275 HE on a 90 nm production node using 233 million transistors. The multiplier is locked on Opteron X2 275 HE, which limits its overclocking potential.
With a TDP of 55 W, the Opteron X2 275 HE consumes typical power levels for a modern PC. For communication with other components in the machine, Opteron X2 275 HE uses a PCI-Express Gen 2 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.
