During this IDF Fall 2006 we had the chance to benchmark the first Intel quad-core CPU for desktops, Core 2 Extreme QX6700 (codenamed Kentsfield) – which will be released only in November –, and compare its performance against a Core 2 Extreme X6800, today’s fastest CPU available. Let’s take a look!

We have already explained the technical details of the forthcoming Core 2 Extreme QX6700 on our Intel Quad-Core CPU Overview and Roadmap article. Basically, it will feature a 8 MB L2 memory cache (2x 4 MB), will run with a 1,066 MHz front side bus and will have its clock multiplier unlocked.

Below you will find some screenshots of the system with the Core 2 Extreme QX6700 installed.
