AMD Athlon 64 X2 3800+
Next up, 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 a gargantuan "Ultra" model that is comprised of over 16 billion polys...
The two Kribibench models we rendered to generate the scores above told essentially the same story. When rendering the "Sponge Explode" model, the Athlon 64 X2 3800+ couldn't hand with the X2 4800+, but it had no trouble outperforming the Pentium D 820. In fact, the Athlon 64 X2 3800+ finished that test with a frame rate about 16.5% higher then the Pentium D. Rendering the Ultra model was much more taxing, but the performance trend was exactly the same.
