LAME MP3 Multi-threaded Encoding
In our custom LAME MT MP3 encoding test, we convert a large WAV file to the MP3 format, which is a 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 is an open-source mid to high bit-rate and VBR (variable bit rate) MP3 audio encoder that is used widely around the world in a multitude of third party applications.
In this test, we created our own 223MB WAV file (a hallucinogenically-induced 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, listed in seconds. Shorter times equate to better performance
In this test there was very little separation between the X58/Core i7-based motherboards in our test group. However, the EVGA board, for whatever reason, was able to complete the multi-threaded run a couple of seconds faster than the Gigabyte and Intel boards and offer a photo-finish win versus the Asus board. Obviously this performance variance in negligible though. It's also interesting to note that the Core i7 is close to 20% faster than the Core 2 Quad in this usage model.
