Intel's compute features are in a separate open source package called Intel Graphics Compute Runtime.[1] Integrated graphics from 2014 (Broadwell) and later are supported. Support for discrete graphics (2020 onward) is in development.[2]

AMD provides an open source OpenCL solution for Linux called ROCm, but the project is too limited to be helpful in many use cases. ROCm supports a total of 6 GPU models, all from previous generations,[3] and does not support GUI-based software applications such as Blender.[4]
