The AMD Athlon 64 X2 6400+ is a desktop processor with 2 cores, released in 2007 at an MSRP of $225. It is part of the Athlon 64 X2 lineup, using the Athlon 64 X2 platform, and fits the AM2 socket. Internally, it is built on the "K8L" architecture. It operates at a fixed 3.2 GHz. AMD manufactures the "K8L" 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 DDR2 memory. With a TDP of 125W, the Athlon 64 X2 6400+ 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/core of L1 and 1MB/core of L2 cache. There is no L3 cache on this processor.
