Blender 2.81 CUDA vs. OptiX Performance

But the OptiX support isn't quite perfect... In the Barbershop scene is the sole case where I noticed OptiX regressing compared to the CUDA performance. Clearly something is awry with OptiX here, but then again this back-end is technically in alpha stage for Blender 2.81.

The OptiX performance was back on-track with the Pabellon Barcelona scene and rendering much faster than the CUDA code-path.

If taking the geometric mean of all those runs and sorting by performance, here is how the positioning is looking for NVIDIA from Maxwell through Turing RTX graphics cards. The OptiX back-end for Blender opens up a whole new realm for speedy rendering that an RTX 2060 with OptiX can even outperform the GTX 1080 Ti with CUDA. Mighty fine showing aside from the regression with the barbershop scene, but considering this is first-cut support in Blender 2.81, we're excited to see how the performance will evolve for Blender 2.82.
