AMD · Athlon II · 2010 · AM3
The AMD Athlon II X4 640 is a desktop processor with 4 cores, released in 2010 at an MSRP of $99. It is part of the Athlon II lineup, using the Athlon II X4 platform, and fits the AM3 socket. Internally, it is built on the "K10" architecture. It operates at a fixed 3 GHz. AMD manufactures the "K10" silicon on a 45nm process node. Its multiplier is locked, so any overclocking has to come from raising the base clock rather than the multiplier. This processor supports DDR3 memory. With a TDP of 95W, the Athlon II X4 640 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 2MB of L2 cache. There is no L3 cache on this processor.
