Athlon 64 X2 Energy Efficient Processors
Lame MP3 Multi-Threaded
In our custom LAME MT MP3 encoding test, we convert a large WAV 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 created our own 223MB WAV file (a never-ending Grateful Dead jam) and converted it to the MP3 format using the multi-thread capable LAME MT application in single and multi-thread modes. Processing times are recorded below. Once again, shorter times equate to better performance.
The results of our custom LAME MT MP3 encoding benchmark, whether in its single- or multi-threaded mode, tell essentially the same story as the Photoshop 7 benchmark on the previous page. The Core 2 Duo E6700, Pentium Extreme Edition 965, and the A64 X2 5000+ were all able to complete the encoding process faster than the low-power Athlons, but they do so because they are clocked higher and consumer more power. Try to run one of those CPUs at the lower voltages the 4600+ and 3800+ require, and they may not even remain stable.
