I have an RX 580 running amdgpu open source driver. Xorg and OpenGL support is supperb. But OpenCL sucks big way. There is clover, the open source OpenCL implemention of Mesa, but it is totally unusable for anything serious (even OpenCL 1.1 and OpenCL 1.2). Even clinfo would dump core after displaying lots of infos on the GPU. Then there is AMD-APP, which is supposed to support OpenCL 1.2, but that is part of closed driver amdgpu-pro, which runs only on Linux. I'm dual-booting FreeBSD and Manjaro-Linux just to be able to do OpenCL stuff on Linux. But even there, the opencl-amd AUR package which extracts the OpenCL bits from the amdgpu-pro driver and puts them into the (much better and newer) amdgpu driver causes some packages like, say, xmr-stak-amd to generate invalid results on the GPU... which is, according to xmr-stak-amd developer due to the opencl support in amdgpu-pro 18.x driver to be broken, and that one has to downgrade to amdgpu-pro 17.x opencl. It is not easy to use OpenCL on AMD right now. They are developing the ROCm platform[1], which looks promising, but they are not there yet.
