Radeons compute units are in-order though, in the usual sense of the word, and I'd love to hear it if there really was an out-of-order GPU. It'd be rather surprising. One thing that they do have to deal with data dependencies is that load (and texture fetch etc.) instructions don't block. Instead, there's a separate instruction for waiting on the result of a previous load. |
