If I remember correctly, CUDA is pretty tightly tied to Nvidia’s GPU architecture, so it would be very difficult to get the same things to run on AMD chips without them making huge changes to conform to Nvidia’s way of doing things. I think there have been a few projects that try to translate CUDA stuff into OpenCL or other AMD-compatible compute platforms.
