Imagine GPU as painter and CPU as a director: if system is balanced, director sends just enough requests to the painter so that painter is always busy painting and director is busy prepairing new orders. If CPU is bottlenecking, painter paints too quickly and stays idle, while director has trouble prepairing orders quckly enough and is always busy prepairing them. Painter could paint more, but it cannot without directions on what to paint. If GPU is bottlenecking, director has to spend time doimg nothing waiting for the painter to finish, before giving him a new order.
