Benchmarking - Video Encoding Tests
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.
