Summary: AMD works if you spend 500m USD+ with them. Then they'll throw an army of their own software engineers into the contract who will hold your hand every step of the way, and remove all the jank for you. By contrast, since at least 10 years ago, I could buy any GTX card and CUDA worked out of the box, and that applied right down to a $99 Jetson Nano.
AMD's strategy looks a lot like IBM's mainframe strategy of the 80s. And that didn't go well.
