AMD · Opteron · 2009 · Socket F
The AMD Opteron 8425 HE is a server processor with 6 cores, released in 2009 at an MSRP of $1,514. It is part of the Opteron lineup, using the Opteron 8400 platform, and fits the Socket F socket. Internally, it is built on the "K10" architecture. It operates at a fixed 2.1 GHz. AMD manufactures the "K10" silicon on a 45nm process node. This processor supports DDR2 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 79W, the Opteron 8425 HE sits in a typical power envelope for a modern desktop CPU. The cache hierarchy consists of 128KB/core of L1, 512KB/core of L2, and 6MB of L3 cache.
6-core K10 Opteron (Istanbul) at 2.1GHz on Socket F, launched July 2009. Istanbul was the first six-core Opteron, adding HT Assist to cut cache-coherency traffic in multi-socket systems. It scales to four- and eight-socket systems. The HE (high-efficiency) bin trades clock headroom for a lower 79W TDP.
