Did you actually test this or what do you base this documentation change on? As far as I know the OpenCL kernels are specifically-tuned for mobile GPUs and some Intel iGPUs, nothing else.

The opencl back end really is only interesting for pre-gcn GPUs not pre rdna as all gcn GPUs support the vulkan back end which is in mutch better shape.

Then what is the point of this PR? You cannot document something that you do not know and cannot test.
