GPU vs CPU - GPU rendering vs Software CPU rendering
Scene 1 - up to 6x faster
Unbiased rendering and Physically based full global illumination
The most similar render for compare the speed and quality is CPU render, Arnold, because it uses also Path tracing.
The scene is very complicated for ray tracing and all scene is lit by indirect - 4x bounced light with brute force.
In FurryBall setup there is 400 rays for 14 min render and 200 rays for 6:30 render with our Noise reduction filter.
200 rays + Noise reduction
400 rays - NO Noise reduction
Scene 2 - 14x faster
The simple cartoon-like scene without reflections. Just two lights and raytraced shadows.
Intel Core i7-930 2,80 GHz, 16 GB RAM, Nvidia Geforce GTX Titan - 6 GB Memory
Because every renderer has totally a different setting, there is no possible to have the same settings. We tried to set the optically similar quality for each renderer. We set brute force in all renderer (without any tweaking).
