Shuttle SN25P XPC (nForce 4 Ultra)
Windows Media Encoder & LAME MP3
We continued our testing of the Shuttle SN25P XPC with a video encoding benchmark based on Windows Media Encoder 9. In this test, we ran the Windows Media Encoder 9 portion of the WorldBench 5 suite; encoding times were recorded in seconds. Lower times indicate better performance.
In WorldBench 5.0's video encoding performance module, the 3.73GHz Pentium 4 Extreme Edition cruised right past all of the A64s, besting the fastest Athlon by almost a minute. The SN25P finished in a two-way tie for the top spot among the three Athlon powered systems, however, with a total encoding time of 386 seconds.
In our custom Lame MP3 encoding test, we convert a large digital audio file to the MP3 format, which is a very popular scenario that many end users work with on a day-to-day 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. Shorter times equate to better performance.
If you disregard the Pentium 4's performance here, you'll see that the Shuttle SN25P XPC finished our custom LAME encoding test slightly ahead of the other AMD based systems, with a total time of 2 minutes and 21 seconds. The SN25P's lead was only 2 seconds though, which is not an eternity by any stretch of the imagination, but its the fastest Athlon powered system nonetheless.
