Benchmark Results: Audio And Video Encoding
While standard media-oriented applications might not appear important in a graphics configuration comparison, we’ve heard that CrossFire management can have a slight impact on a few of these tests. We also wanted to see how the top-end-mobile Core i7-940XM would stack up against our lowest-frequency desktop Core i7.
Lower is better for encoding times, and the mobile processor uses Intel’s top Turbo Boost mode to overwhelm the single-threaded Apple iTunes bench.
A lower non-Turbo speed hinders the mobile platform in the superbly-threaded HandBrake encoding test.
A lack of development has kept Xvid from taking advantage of four-core, eight-thread processors, and it appears that both the desktop and mobile processors run the same speed throughout that application. DivX usually isn’t the best example of a multi-threaded application, yet it beats Xvid in revealing the notebook processor’s heavy reliance on light-load Turbo Boost frequencies.
MainConcept shows, once again, that when all four cores are busy, the mobile processor isn’t able to use Turbo Boost to its advantage.
