AMD · Opteron · 2005 · Socket 940
The AMD Opteron 254 is a server processor with 1 core, released in 2005 at an MSRP of $851. It is part of the Opteron lineup, using the Opteron 200 platform, and fits the Socket 940 socket. Internally, it is built on the "K8" architecture. It operates at a fixed 2.8 GHz. AMD manufactures the "K8" silicon on a 90nm process node. This processor supports DDR memory across 2 channels, with ECC support standard for data integrity in server workloads. It supports both single-socket (1P) and dual-socket (2P) configurations. With a TDP of 92.6W, the Opteron 254 sits in a typical power envelope for a modern desktop CPU. The cache hierarchy consists of 128KB/core of L1 and 1MB of L2 cache. There is no L3 cache on this processor.
1-core K8 Opteron (Troy) at 2.8GHz on Socket 940, launched August 2005. Troy is the 90nm dual-socket refresh of the original Opteron, adding SSE3 and higher clocks than the 130nm parts. It supports up to two-socket systems.
