Encoding Time Tests
We continued testing with another module from World Bench 5, this time based on Windows Media Encoder 9. PC WorldBench 5's Windows Media Encoding test reports encoding times in seconds, and like the tests on the previous page, lower times indicate better performance here.
The overall spread in this test was a mere five seconds, bookmarked on both ends by the Asus boards. In the benchmarks so far, we've seen very close groupings of the boards performance-wise, with an ever so slight edge going to the nForce4-SLI boards.
In our custom Lame MP3 encoding tests, we convert a large WAV file to the MP3 format, which is a very popular scenario that many end users work with on a regular basis, to provide portability and storage of their digital audio content. In this test, we chose a large 223MB WAV file (a never-ending Grateful Dead jam) and converted it to the MP3 format. Processing times are recorded below. Once again, shorter times equate to better performance.
Not much can be said for the MP3 encoding tests. Each board completed the conversion in either 2 minutes 25 seconds or 2 minutes 26 seconds. Given some room for error, we may as well call this benchmark a four-way tie.
