MSI P45 Platinum and Diamond Motherboards
3DMark06 and LAME MT MP3 Encoding
3DMark06's built-in CPU test is a multi-threaded DirectX gaming metric that's useful for comparing relative performance between similarly equipped systems. This test consists of two different 3D scenes that are processed with a software renderer that is dependent on the host CPU's performance. Calculations that are normally reserved for your 3D accelerator are instead sent to the CPU for processing and rendering. The frame-rate generated in each test is used to determine the final score.
The CPU performance test resulted in not only close scores for the two MSI P45 boards, but all the boards used for comparisons as well. Oddly, the top score came from the oldest board, the ASUS Blitz Formula using the P35 chipset - just what the MSI P45 boards are replacing. Yet, these same boards outran the higher-end X48 boards with a 1-10 Mark difference. Between the two, the Platinum board has the slightest of edges.
LAME MT 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 and converted it to the MP3 format using this multi-thread capable application in single and multi-thread modes. Processing times are recorded below, listed in seconds. Here, shorter times equate to better performance.
There's little to be gleaned from the LAME MT Encoding results. Whether using a single threaded pass or a multi-threaded one, the times from start to finish almost always turned out to be exactly the same, with the two ASUS boards off by a second during one of the runs.
