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 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. Once again, shorter times equate to better performance.
Our custom LAME MT MP3 encoding benchmark showed absolutely no variation between the three Intel-powered test systems.
Sony's Vegas DV editing software is heavily multi-threaded 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.
Our Sony Vegas video rendering benchmark showed very little variation between the Intel-based systems. The X48-based P5E3 Premium technically finished 1 second faster than the X38s, but we've seen variations larger than that from test run to test run.
