AMD HIP vs. NVIDIA CUDA vs. NVIDIA OptiX On Blender 3.2

Last week with the release of Blender 3.2 bringing AMD HIP support for Linux to provide for Radeon GPU acceleration, I posted some initial benchmarks of AMD Radeon RX 6000 series with HIP against NVIDIA RTX with OptiX. There was interest by some Phoronix readers in also seeing NVIDIA CUDA results even though OptiX is in good shape with RTX GPUs, so with that here are results of NVIDIA CUDA vs. NVIDIA OptiX vs. AMD HIP with Blender 3.2 on Ubuntu Linux.
