ATi RADEON XPRESS 200 Series: AMD Platform Chipsets

Windows Media Encoder 9 & LAME MP3

We continued our testing of the ATi RADEON XPRESS 200 chipset with a video encoding benchmark using Windows Media Encoder 9.  In this test, we took a 416MB Digital Video file and encoded to WMV9 streaming format.  The encoding times were recorded in minutes:seconds, with lower times indicating better performance.

Somewhat surprisingly, the RADEON XPRESS 200 finished just slightly ahead of the other AMD based test systems in the WME 9 test when using the IGP.  Its margin of victory was only 1 second, but score one for the IGP nonetheless.  With a discreet graphics card installed, the RADEON XPRESS 200 performed on par with the nForce 3 Ultra.

Converting A Large WAV To MP3

Next, we did some audio encoding with LAME MP3.  LAME MP3 is relatively new to our test suite, but we thought it was an important component to include as a performance metric.  Converting audio files to MP3 format is a very common task that many end users perform on a regular basis to facilitate portability and storage of their digital audio content.  In this test, we used a large 223MB WAV file (a never-ending Grateful Dead jam) and converted it to the MP3 format.  Processing times are recorded below in minutes:seconds, and once again, shorter times equate better performance.

All of the Athlon 64 powered systems performed similarly in our custom LAME MP3 encoding benchmark, finishing the encoding process with 2 seconds of each other.  Once again, when using the IGP, the RADEON XPRESS 200 manages to squeak passed the discreet card, but the nForce 3 Ultra posted the fastest time for any of the AMD based systems here.
