I think Intel is still pushing opencl on GPUs. Maybe with other layers on top. Sycl or oneapi or similar. AMD mostly shares one implementation between hip and opencl so the base plumbing should work about as well on either, though I can believe the user experience is challenging. I wrote some code that compiles as opencl and found it an intensely annoying experience. There's some C++ extension model to it now which might help but it was still missing function pointers last time I looked. My lasting impression was that I didn't want to write opencl code again.
