Dell XPS 630 Gaming Desktop System
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.
Dell's XPS 630 smoked our zero-point system in 3DMark06 - at least when CPU performance is the sole factor. Had the graphics card factored into the equation, the numbers would have been a bit more balanced.
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.
Our custom LAME MT benchmark resulted in the XPS 630 completing each MP3 conversion only 2 seconds or so quicker than our reference system. Although it could be expected that the single-threaded run should be slightly quicker since the CPU is running just that much faster, the multi-core timings ending up so close is the result of LAME MT using a maximum of only two threads.
