The Core 2 Quad Q8400 VS Phenom II 940

Q8400 quad-core chip running at 2.66GHz with a 2MB L2 per pair of cores (4MB total). It’s like two Pentium Dual Core processors on a single package.

These chips actually have a 6MB L2 but with 2MB disabled either because they have irrecoverable defects in the cache or simply to hit the right price point. In other words, the Q8400 is literally a Q9400 but with 2MB of its L2 disabled.
