LAME MT: Single & 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.
LAME MT thrives on one thing, core CPU clock speed. This is the one test that allows Intel's Pentium Extreme Edition 965 at 3.73GHz to shine. The EE 965 offers a solid 6 second advantage over the FX-62 which equates to about 15% more throughput. The rest of the numbers speak for themselves. There is no tangible advantage for MP3 encoding with multi-threaded or single threaded LAME, for the new AM2 platform.
