we know the performance of the 7950, 7970, 580 and 480.
At that point we know the difference between the 480 and 580, 580 and 7950, 580 and 7970 and 7950 and 7970...

So if we assume valid results, than the scale, the resolutions, the drivers are known and fixed. Using a different scale would make the results of the known invalid.
