Here we look at a small selection of productivity benchmarks, starting with Blender 2.90 and OctaneBench.
Blender rendering performance is strong for the RTX 3070. Using CUDA, it offers a huge 39% reduction in total render times compared to the RTX 2080 Ti, while it takes 26% longer than the RTX 3080. Using Optix instead of CUDA sees the 3070 reduce the overall render time by 35% when compared to the 2080 Ti.
As for Octane, render performance for the RTX 3070 with RTX Off is bang in line with the RTX 2080 Ti. The RTX 3070 does pull ahead when RTX is enabled, though, with its score increasing by 16%.
