Multithreaded performance
Our WAV-encoding test is multithreaded but uses only two cores concurrently. The DivX test, which utilises all four cores, lets the quad-core-equipped machines really show the dual-core E6700 a clean pair of heels.
The CINEBENCH and POV-ray tests are also multithreaded. As such, it's hard to beat a machine that uses a quad-core processor operating at 3.5GHz.
