AMD · Opteron · 2004 · Socket 940
The AMD Opteron 146 HE is a server processor with 1 core, released in 2004 at an MSRP of $733. It is part of the Opteron lineup, using the Opteron 100 platform, and fits the Socket 940 socket. Internally, it is built on the "K8" architecture. It operates at a fixed 2 GHz. AMD manufactures the "K8" silicon on a 130nm process node. This processor supports DDR memory across 2 channels, with ECC support standard for data integrity in server workloads. It supports single-socket (1P) configurations. With a TDP of 55W, the Opteron 146 HE is an efficient chip suitable for modest cooling solutions. 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 (SledgeHammer) at 2GHz on Socket 940, launched February 2004. The original 130nm Opteron that introduced AMD64 to the server market in 2003, with an on-die memory controller and HyperTransport links in place of a front-side bus. It is limited to single-socket systems. The HE (high-efficiency) bin trades clock headroom for a lower 55W TDP.
