Multi-threaded focus
The WAV-encoding test is multithreaded, but only uses two cores. That's why, again, the Core 2 Duo E6700-powered HEXUS system is faster.
The DivX encode, on other hand, uses all four of the Q6600's cores to good effect, beating out the faster-clocked E6700 by over 20 seconds.
The newest iteration of CINEBENCH, R10, renders a scene with greater complexity. The quad-core Q6600 easily outmuscles an E6700 here.
The quad-core CPU also outperforms the faster dual-core in POV-Ray. Remember, though, that we're using a 64-bit executable for the HEXUS system and its performance is a little lacking compared to what we've seen from 32-bit Vista - an E6700 shouldn't be half as slow as a Q6600.
