Blender is an extremely popular free and above all open source 3D suite. It supports almost the entire range of 3D pipeline modeling, rigging, animation, simulation, rendering, compositing and motion tracking, video editing and 2D animation. In other words, almost everything that the topic offers. Since the release of the 2.81 update, Blender now supports RTX-accelerated rendering with the NVIDIA OptiX rendering API in the Cycles renderer.
This accelerates render times on NVIDIA’s RTX GPUs and speeds up rendering output tremendously compared to CUDA or OpenCL. Measuring the final render times is a good way to evaluate the capabilities of GPUs when it comes to working efficiently and with as little interference as possible.
What is noticeable in these benchmarks is the OpenCL implementation of the Radeon VII, which in some situations almost falls into a black hole compared to the navigation charts. One has the feeling that it simply stopped optimizing somewhere. Not a good sign for the upcoming Radeon Pro VII.
