Application Benchmarks: Media Encoding
We started with the iTunes benchmark, which measures how long it takes iTunes to convert a half-gigabyte WAV file to AAC:
The overclock gave us a performance benefit that mirrors the Sandra CPU benchmarks: about a 44% increase.
Lame delivers a similar performance increase. Even though we haven’t achieved an epic overclock here, it’s still a success in that the impact on real-world usage is huge.
Next, let’s move on to video encoding with DivX and Xvid files using TMPEG.
Our overclock is giving us a solid 40% speed increase here. It’s becoming clear that media encoding applications are dependent on CPU speed more than anything else.
Mainconcept demonstrates the same 40% speed increase when converting an MPEG2 video file to H.264.
