LAME MP3 Encoding and 3DMark05
In our custom Lame MP3 encoding tests, we convert a large digital audio file to the MP3 format, which is a very popular scenario that many end users work with on a regular basis, to provide portability and storage of their digital audio content. In this test, we chose a large 223MB WAV file (a never-ending Grateful Dead jam) and converted it to the MP3 format. Processing times are recorded below.
Only 3 seconds separated the two systems, with the fastest time going to the Epox 5LWA+. This delta in performance (about 2%) is so slight that most users would not even notice when converting files, especially smaller ones.
3DMark05's CPU test module gives us an idea of how these systems will perform in a DirectX gaming environment, with the main emphasis of the test focused on CPU throughput and overall system bandwidth. This test consists of two different 3D scenes that are generated with a software renderer, which is dependant on the host CPU's performance. This means that the calculations normally reserved for your 3D accelerator, are instead sent to the central processor. The number of frames generated per second in each test, are used to determine the final score.
3DMark05 was our first taste of gaming, although we focused solely on CPU performance rather than running the entire suite of tests. It was in this test that we saw the first measurable separation between the two systems. Although we had typically seen differences in previous benchmarks along the lines of 1-2%, we saw the Shuttle lagging behind the Epox board in 3DMark05 by double that amount.
