AMD · Phenom II · 2009 · AM3
The AMD Phenom II X4 945 is a desktop processor with 4 cores, released in 2009 at an MSRP of $139. It is part of the Phenom II lineup, using the Phenom 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 Phenom II X4 945 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, 2MB of L2, and 6MB of L3 cache.
95W mainstream quad-core — one of the most popular Phenom II builds for budget gaming systems.
