Intel · Core 2 Quad · 2009 · LGA775
The Intel Core 2 Q9505 is a desktop processor with 4 cores, released in 2009 at an MSRP of $213. It is part of the Core 2 Quad lineup, using the Core 2 platform, and fits the LGA775 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 Q9505 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 3MB of L2 cache. There is no L3 cache on this processor.
Yorkfield with 3MB L2 per die at Q9550 clocks. Budget alternative to the Q9550 which has 6MB L2 per die.
