AMD · Athlon 64 · 2005 · 939
The AMD Athlon 64 3700+ (S939) is a desktop processor with 1 core, released in 2005 at an MSRP of $365. It is part of the Athlon 64 lineup, using the Athlon 64 platform, and fits the 939 socket. Internally, it is built on the "K8" architecture. It operates at a fixed 2.2 GHz. AMD manufactures the "K8" silicon on a 90nm process node. Its multiplier is locked, so any overclocking has to come from raising the base clock rather than the multiplier. This processor supports DDR memory. With a TDP of 89W, the Athlon 64 3700+ (S939) sits in a typical power envelope for a modern desktop CPU. This processor has no integrated graphics — a discrete GPU is required. The cache hierarchy consists of 64KB of L1 and 1MB of L2 cache. There is no L3 cache on this processor.
San Diego die — 1MB L2 cache vs 512KB on Venice. Same 2.2 GHz clock as 3500+ but double the L2.
