No, it is almost certainly not 2 times the work, due to the reasons I pointed out.

Also note, that from a computer science standpoint, it is extraordinarily unlikely that double a screen's resolution of any rendering system will 1/2 the frame rate.  Increasing the resolution pretty much ONLY affects the fragment (or pixel if you prefer) shader's performance as more fragments are sent to the shader for processing, the vast majority of individual time slices that compose the frame's render time will not care about the resolution what so ever.  Fragment shaders are a significant chunk of the total fram time, but certainly not 100% and probably not 50% for most games.

You're not getting it. I know how a GPU works and what all the parts do, and the effect on performance. All that is nothing to my actual point that a "single processor" operating on a 2x larger screen is still 2x the work for a completely different image of equal complexity being on the other half (notice I said it's NOT 2x the work for a blank screen, and infer that there is a gradient of work between those two if some is shared), while the OP article claims it's insufficient as if 2 GPUs would be better when they are not due to overhead.

Also thre is no such thing as a fragment shader or vertex shader any more. All the computational units can perform both tasks.

All I will say is, the OP article is wrong about that the fact that a single GPU can run these fine without issues. 2 GPU's better? Describe better? Really can mean anything. He blows my mind. I will do the same now. 3 GPU's is even better! One GPU is plenty to handle this application. With news on the lack in  power, makes me worried about the end specs of the WiiU. Seems underpowered.
