Tuning Cool'n'Quiet: Maximize Power And Performance, Part 2

Benchmark Results: 1080p AVI With VirtualDub And XviD

For Xvid encoding, we’ve selected the unrestricted profile with the general purpose preset. The encoding was done with a fixed quantizer of one, one pass, quality-based. Everything else was set at its default value.

Xvid actually requires less processing power than DivX. Encoding time is also shorter. The resulting file is slightly larger, but not by much.

It looks like DivX isn't the only codec having problems with the Phenom II X3 710. We see a larger gap between both the Phenom II X4s and the dual-core Athlon X2/Athlon II. So, much like test results with multi-threaded applications, the Phenom II X4s end up as the most energy efficient processors.

    I would have liked to see how the quad 810 processor would have gone, considering it is just one peg above the triple core 720, and a few pegs below the 945 and 955 - perhaps it yields a nice balance/performance/voltage ratio? Certainly interesting given that it is a 95w processor, but possessing four cores, I guess that it would have trumped the 720. Maybe AMD sponsors these articles, and have to sell a few more 720s first.

    AMD 810 FTW

    I doubt AMD sponsors these. Have you seen how poorly the 710 does at DivX? I doubt that DivX will change their code for triple core CPUs, so the 720 will behave similarly to the 710. In addition, this guide is an AMD-only guide.
