Blender 3.2 Performance With AMD Radeon HIP vs. NVIDIA GeForce On Linux

At least the Radeon HIP back-end is finally exposed under Linux for those wanting to make use of it. Hopefully the back-end as well as the ROCm/HIP code itself will continue to mature nicely. Blender developers are also still exploring Vulkan support and other improvements that may hopefully pan out in time for offering nice cross-vendor support. Intel is also working on SYCL + oneAPI support for Blender for Intel Arc Graphics acceleration.

At least the Radeon HIP support in Blender 3.2 can work on Linux and with a high-end GPU is faster than CPU-based rendering, but the NVIDIA support with its OptiX and CUDA back-ends continues to prove superior at this stage. It's also unfortunate that deploying the HIP Linux software support outside of AMD's officially supported Linux distributions can be a pain and similarly that more than one month past the Ubuntu 22.04 LTS release, there still isn't any official AMD support yet for this latest version of Ubuntu Linux. And also unfortunate with RDNA1 GPUs and prior I am just getting segmentation faults with Blender 3.2 where as the NVIDIA supported GPU range is very robust and spans their entire portfolio for generations.

Lastly, for those curious, below is a look at the GPU power consumption and thermal data for the entire span of different Blender test scenes that were benchmarked for this Blender 3.2 Linux comparison.
