This is obviously game dependent, but if the games they looked at scaled better with a 6.6% upclock than a 16.6% increase in ALU, then it suggests they were being limited more by other parts of pipeline. ROPs is the easy one to finger.
It's interesting that in article where Microsoft want to promote the "balance" of their systems, the numbers that they spit out would suggest otherwise. If you're so fill limited that adding extra functional units has barely any increase in performance then how can you argue that you're balanced at all? All that would suggest is that you have a serious problem with a bottleneck elsewhere in the pipeline.
