LAME MT & Futuremark 3DMark Vantage
In our custom LAME MT MP3 encoding test, we convert a large WAV file to the MP3 format. This simulates a common scenario that many of us users work with on a regular basis to provide portability and storage of digital audio content. LAME is an open-source, mid- to high- bit-rate and VBR (variable bit rate) MP3 audio encoder that is widely used around the world in a multitude of third party applications.

In this test, we created our own 223MB WAV file and converted it to the MP3 format using the multi-thread capable LAME MT application in single and multi-threaded modes. Processing times are recorded below, listed in seconds. Shorter times equate to better performance.
This LAME MT test is a measure of almost pure processor speed, and is not impacted significantly by L2 cache size or the presence of more than two cores. This test shows the QX9770 processor running at 3.8GHz edging out the Core i7 920 over clocked at 2.93GHz by a few seconds on both the single- and multi-threaded tests. You’ll also notice that the dual-core, E6850 didn’t fare significantly worse than the quad-core i7 920. Many mainstream applications still don’t support multi-threading with more than two cores. As a result, when it comes to encoding audio or video, the results shown here are pretty indicative of the performance you could expect from similar applications.

3DMark Vantage is the latest version of Futuremark's synthetic 3D gaming benchmark. This benchmark is constrained to Windows Vista-based systems because it uses some advanced visual technologies that come by means of DirectX 10, which isn't available on previous versions of Windows. With this latest version of the benchmark, Futuremark added two new graphics tests, two new CPU tests, and several new feature tests, along with support for the latest PC hardware. We used the Performance preset for our test.
