The AMD Opteron X2 265 HE was a server/workstation processor with 2 cores, launched in August 2005. 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 265 HE CPUs can work together in a multi-processor (SMP) configuration. Opteron X2 265 HE has 1 MB of L2 cache and operates at 1800 MHz. AMD is making the Opteron X2 265 HE on a 90 nm production node using 233 million transistors. The multiplier is locked on Opteron X2 265 HE, which limits its overclocking potential.
With a TDP of 55 W, the Opteron X2 265 HE consumes typical power levels for a modern PC. For communication with other components in the machine, Opteron X2 265 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.
