openSUSE provides some packages with GPU:ROCm repository.
For instance, installing AMD HIP (openSUSE Software):
zypper addrepo https://download.opensuse.org/repositories/science:GPU:ROCm/openSUSE_Factory/science:GPU:ROCm.repo
zypper refresh
zypper install hip
Add GPU:ROCm repository into your system to see all available packages. This openSUSE-Factory repo is incompatible with Leap.
After getting HIP you can run Blender & other stuff on HIP (not tested).
After installing ZLUDA you can get CUDA support and run Blender on CUDA backend. Full path will be Blender → CUDA → ZLUDA → HIP → GPU. Blender runs about 20% faster on CUDA-ZLUDA compared to direct HIP usage.
