Zig and GPUs

While I admire the work of hobbyists it still looks like C/C++ will be the default until a GPU vender makes the decision to support these libraries.

From my understanding, Vulkan and OpenGL are nice but the true performance lies in the specific toolkits (ie CUDA, Metal).

Wrapping the vendor provided frameworks is liable to break and that isn't tenable for someone who wants to do this on a professional basis.

I am a complete noob in GPU but is AMDGCN the older generation with the new one being RDNA? If you generate a binary for AMDGCN, will it run on the newest cards?

Also, I though that these GPU ISAs were "proprietary". I wonder how reliable the binary generation can be.
