It is part of the Core 2 Extreme lineup, using the Core 2 platform, and fits the LGA775 socket. Internally, it is built on the "Yorkfield" architecture. It operates at a fixed 3 GHz. Intel manufactures the "Yorkfield" silicon on a 45nm process node. The multiplier is unlocked, making overclocking straightforward. This processor supports DDR2/DDR3 memory. With a TDP of 130W, the Core 2 Extreme QX9650 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 6MB of L2 cache. There is no L3 cache on this processor.
First Yorkfield (45nm) Extreme Edition quad-core. 6MB L2 per die = 12MB total. Notable step up in efficiency from the 130W Kentsfield despite same TDP rating.
