Kribibench 3D Rendering
Next we ran Kribibench, a 3D rendering benchmark produced by the folks at Adept Development. Kribibench is an SSE aware software renderer. 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 very large "Ultra" model that is comprised of over 16 billion polygons.
Dual core processors rule the roost with Kribibench but there's an interesting contrast between our Sponge model rendering test and the Ultra model rendering test, which is significantly more taxing. With the Sponge model, the Athlon 64 FX-60 and 4800+ hold approximately a 19% advantage over the fastest Pentium EE 955 score but the Ultra model shows a much tighter grouping of performance with only a 1.5% variance between the Athlon 64 FX-60 and the Pentium EE 955. Perhaps we're seeing the Athlon 64 system architecture running out of overall memory bandwidth here, reining in its performance significantly versus the lighter workloads in the Sponge test model, which obviously allows all the CPUs tested to stretch their legs a bit more.
