Cinebench 2003 & 3DMark05: CPU
The Cinebench 2003 benchmark is an OpenGL 3D rendering performance test, based on the commercially available Cinema 4D application. This is a multi-threaded, multi-processor aware benchmark that renders a single 3D scene and tracks the length of the entire process. The time it took each test system to render the entire scene is represented in the graph below (listed in seconds).
We've got another nail-biter here. The Cinebench 2003 rendering benchmark had the nForce 4 powered Gigabyte K8NXP-SLI and Radeon Xpress 200 powered Sapphire PI-A9RX480 performing at very similar levels, but the Gigabyte board did have a slight advantage. In the single-threaded test the Gigabyte board finished rendering the scene .2 seconds faster than the PI-A9RX480, and in the multi-threaded tests, the Gigabyte board extended that margin to .3 seconds.
3DMark05's built-in CPU test is a multi-threaded "gaming related" DirectX metric that's useful for comparing relative performance between similarly equipped systems. 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's CPU performance module gave a slight advantage to the nForce 4 powered Gigabyte K8NXP-SLI. In this test, the K8NXP-SLI finished with a score of 5378, and advantage of 84 points or 1.5%. Once again, although the nForce 4 based board technically outran the Radeon Xpress 200 based board, the margin of victory was quite small, and falls well within the margin of error in this test.
