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.

With Windows Media Encoder, the S-presso gave its best performance with integrated graphics, completing the test in 3:37.  Second was the Abit AI7 while we saw the slowest results with the S-presso and the 6800, taking full 10 seconds longer to complete.

With XMPEG, the scores were more in-line with what we would expect.  The S-presso turned out the best overall score with the GeForce 6800, trailed by the AI7.  Overall, however, we're talking a matter of three seconds between the three scenarios.
