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

So long story short, even if using the NVIDIA CUDA back-end rather than the optimal NVIDIA OptiX back-end, it really doesn't change the outcome that the NVIDIA Blender performance for now is much faster than what is offered by AMD HIP for Radeon GPU acceleration on Windows and Linux.

For those interested, this is the breakdown of the GPU power consumption and GPU core temperatures as exposed by the respective Linux drivers across the entire duration of all the Blender scenes benchmarked.

Those interested can find more of my Blender CPU and GPU benchmarks along with numbers from the community via this OpenBenchmarking.org test profile page.
