The AMD Opteron 148 HE was a server/workstation processor with 1 core, launched in December 2004. It is part of the Opteron lineup, using the Venus (E4) architecture with Socket 940. Opteron 148 HE has 1 MB of L2 cache and operates at 2.2 GHz. AMD is building the Opteron 148 HE on a 90 nm production process using 106 million transistors. The multiplier is locked on Opteron 148 HE, which limits its overclocking capabilities.
With a TDP of 55 W, the Opteron 148 HE consumes typical power levels for a modern PC. For communication with other components in the system, Opteron 148 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.
