NVIDIA nForce 4 SLI Intel Edition
Windows Media Encoder 9 & LAME MP3
We continued our testing of the NVIDIA nForce 4 SLI Intel Edition reference motherboard with a video encoding benchmark using 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.
The nForce 4 SLI Intel Edition continued its winning ways in the Windows Media encoder benchmark, besting the i925XE based system by 4 seconds when the NF4's memory was clocked at 667MHz, and by 3 seconds when it was clocked at 533MHz. The Athlon 64 powered system lagged behind the Intel based systems by almost a full minute.
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.
Things continued to go the nForce 4 SLI Intel Edition's way in our custom LAME MP3 encoding benchmark. Here though, the nForce 4 Intel Edition was only 1 second faster than the i925XE when running the RAM at 667MHz, and it tied the i925XE when both system had their system memory clocked at 533MHz.
