Virtual Dub
Compression with DivX 6.8 and Virtual Dub is a process which can be executed in a multithreaded way. It is also able to give the CPUs 100 percent load. Therefore we can see how the test scales with clock speeds as well as architectural differences.

WAV to MP3
Still a common application is compressing WAV-audio-files to MP3 or AAC files. At this point we show you how quickly this can be done with which CPU.
