The AMD Opteron 846 HE was a server/workstation processor with 1 core, launched in May 2004. It is part of the Opteron lineup, using the SledgeHammer (CG) architecture with Socket 940. Opteron 846 HE has 1 MB of L2 cache and operates at 2000 MHz. AMD is building the Opteron 846 HE on a 130 nm production process using 106 million transistors. The multiplier is locked on Opteron 846 HE, which limits its overclocking capabilities.
With a TDP of 55 W, the Opteron 846 HE consumes typical power levels for a modern PC. For communication with other components in the system, Opteron 846 HE uses a PCI-Express Gen 2 connection. This processor lacks integrated graphics, you might need a graphics card.
Neither SSE3 nor SSE4 instruction sets are supported, which will lead to problems with games not starting.
