Next up, we ran the Kribibench 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: an "Exploded Sponge" model consisting of over 19.2 million polygons and then its enormous "Ultra" model that comprises over 16 billion polygons.
The two dual-core processors we tested, the Athlon 64 X2 4800+ and the Pentium Extreme Edition 840, crushed their competition in the KribiBench software rendering tests we ran. Disregarding the dominant performance of the dual-core CPUs though, we see that the Athlon 64 FX-57 posted the best framerate in the "Sponge Explode" test when compared to other single-core processors, but it finished just a hair behind the Pentium 4 670 and 3.73GHz P4 EE with the hugely complex "Ultra" model, which can probably be attributed to the benefits of Intel Hyperthreading.
