That's why the immediate future of computational devices is so interesting. Intel tries to evolve CPUs more towards GPUs. Nvidia tries to push GPUs towards CPUs. And AMD might not have the most sophisticated CPU or GPU, but by far the best chance to integrate the two really well.
I find it impossible to predict which of the three approaches is going to win. I don't see clear advantages or disadvantages to either of them.
