Blender 3.3 AMD Radeon HIP vs. NVIDIA CUDA/OptiX Performance

The Radeon HIP back-end continues to improve but for now those just concerned about the outright best performance will find the NVIDIA GeForce performance leading, at least under Linux. Even with the CUDA back-end the NVIDIA performance was in better shape -- such as for the Fishy Cat scene where the RX 6800 XT was again just competing with the GeForce RTX 3070 Ti. For OpenGL and Vulkan workloads on Linux, the Radeon RX 6800 XT is often competing with the GeForce RTX 3090.

With some of the models there were issues rendering on the GFX9/Vega hardware.
