XMPEG 5.03 & Windows Media Encoder 9
Another way to assess a processor's performance is to run a series of video-encoding tests. Video encoding is extremely CPU and Memory bandwidth intensive and has proven to be a good method for gauging overall CPU performance. In the next two segments we ran a series of common encoding tasks and timed the complete process. During the first test, we utilized XMPEG to encode a 110MB MPEG to AVI. The second test used Windows Media Encoder 9 to convert a 416MB AVI to a WMV file.
When it came to encoding video with XMPEG, the Sempron 3300+ and Celeron 3 535 were identical in performance while the Sempron 3100+ trailed the others by 10 seconds.
With Windows Media Encoder, the Sempron 3300+ beat the Celeron D 535 by over 31 seconds. The Sempron 3100+, running a full 1000MHz slower, managed to top the Celeron D by 14 seconds as well. When encoding with Window Media Encoder, L1 cache appears to be more important than clockspeed, as the Sempron's performance has demonstrated.
