The embargo has been lifted on a preview of performance numbers with the new 2.66GHz Core 2 Extreme QX6700 processor. HotHardware showcases Intel quad-core performance from a few different angles, from digital video processing and encoding, to 3D modeling and rendering, along with a few of the more standard benchmarks. the new Intel quad-core puts up performance numbers, depending on the application, at nearly double the performance of a 2.93GHz Core 2 Duo processor based system.
