The AMD Opteron 248 HE was a server/workstation processor with 1 core, launched in March 2005. It is part of the Opteron lineup, using the Troy (E4) architecture with Socket 940. To further increase overall system performance, up to two Opteron 248 HE CPUs can work together in a multi-processor (SMP) configuration. Opteron 248 HE has 1 MB of L2 cache and operates at 2.2 GHz. AMD is making the Opteron 248 HE on a 90 nm production node using 106 million transistors. The multiplier is locked on Opteron 248 HE, which limits its overclocking potential.
With a TDP of 55 W, the Opteron 248 HE consumes typical power levels for a modern PC. For communication with other components in the machine, Opteron 248 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.
