AMD Athlon 64 X2 6000+
LAME MT and Sony Vegas
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
LAME MT processes a maximum of two threads simultaneously, which explains why the dual-core Athlon 64 X2 6000+ and pseudo-quad-core Quad-FX Athlon 64 FX-74 platform performed similarly in this test. Once again though, Intel's Core 2 processors put up the best scores, significantly outpacing the Athlons in both the single and multi-threaded test configurations.

Sony's Vegas DV editing software is heavily multithreaded as it processes and mixes both audio and video streams. This is a new breed of digital video editing software that takes full advantage of current dual and multi-core processor architectures.
The Athlon 64 X2 6000+ completed the Sony Vegas rendering workload about half a minute faster than the Athlon 64 FX-62, but that was the only configuration it outperformed. Because this test is multi-threaded, the quad-core platforms put up the best scores, followed by Intel's dual-core Core 2 processors.
