LAME MT: MP3 Encoding

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. 

LAME MT MP3 Encoding Test
Converting a Large WAV To MP3

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.

 

 

Once again, the new Core 2 Duo E6700 and Core 2 Extreme X6800 processors put up some impressive scores. Our custom LAME MT encoding test had the Core 2 Extreme X6800 finishing the encoding process between 10 and 30 seconds faster than the XE965 and either Athlon 64.  And the Core 2 Duo E6700 was right behind the X6800, trailing Intel's new flagship by only 5 seconds in either test.

We also found that all of the chipsets we tested offered similar performance in this test.  As an additional experiment, we installed Corsair's low-latency 6400C3 kit in the nForce 4 SLIX16 based system, but we didn't see any difference in performance.  In fact, with 2GB of CAS2 RAM installed on the nForce 4 SLIX16 board, it finished in exactly the same amount of time.
