I might be wrong, but I think it depends on the workload.

The ROPs are the units that do the finishing touches and then sends the data to memory, so how many of them determine how many pixels your GPU can actually push in any given clock cycle, no?
Everything else just determine how much work you can do on those pixels pr clock cycle, no?
So in a situation like say low settings high frame rate gaming where you're trying to achieve as many frames every second as possible but where in general there's not really that much going on pr frame wouldn't the GPU be able to make more use of ROPs then other pieces of hardware?

Mind you, this is not something I know much about at all...
But in my mind I just imagine the hardware essentially skipping steps when there's no changes in a particular part of a image.

But please do correct me if I'm wrong...
