Kribibench and 3DMark06
For this next batch of tests, we ran Kribibench v1.1, a 3D rendering benchmark produced by Adept Development. Kribibench is an SSE aware software renderer where a 3D model is rendered and animated by the host CPU and the average frame rate is reported.
We used two of the included models with this benchmark: a "Sponge Explode" model consisting of over 19.2 million polygons and the test suite's "Ultra" model that is comprised of over 16 billion polys.
Kribibench tells an interesting story. In the sponge explode model test, the Skulltrail system performs much like the QX9770, despite the fact that this is a multi-threaded benchmark. With the more taxing Ultra model, however, the Skulltrail rig pulls way out in front. We beleive this is happening because the sponge explode test is completed so quickly, that all eight cores never hit 100% utilization.
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.
3DMark06's built-in CPU performance module had the Skulltrail rig outperforming the next fastest system, the QX9770 by exactly 1500 points, a delta of just over 30%.
