Quote - You think that a GPU is the same as a CPU and that they can run the same code.  You just keep on thinking that then.

They are both processors, just architecturally different because of the different roles they are designed and intended for.
Obviously the same code is not going to run on them in the same way that the same code for different CPU architectures wouldn't run on the another.

If the code is written to take advantage of GPUs then, because of the huge parallel pipeline processing advantage current GPUs have over current mainstream CPUs, then they would have an advantage because that sort of processing architecture suits rendering.
