Higher clocks on Barts help out with the pixel fillrate the same way as the extra ROPs would. So perhaps the optimal amount of ROPs would be somewhere in between 16-32, theoretically speaking.

Otherwise I have a hard time believing a mere 2% difference between the setups when the 5830 can't pull ahead of 5770 more than 10% with 40% more shaders.
