Intel · Core 2 Quad · 2008 · Socket 775
The Intel Core 2 Quad Q9550 is a desktop processor with 4 cores, released in 2008 at an MSRP of N/A. It is part of the Core 2 Quad lineup, using the Core 2 platform, and fits the Socket 775 socket. Internally, it is built on the "Yorkfield" architecture. It operates at a fixed 2.833 GHz. Intel manufactures the "Yorkfield" 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 DDR2/DDR3 memory. With a TDP of 95W, the Core 2 Quad Q9550 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 32KB/core of L1 and 12MB of L2 cache. There is no L3 cache on this processor.
