What was the starting clock where you calculated that 9.5%?? % improvements without a common base will throw you into the wrong conclusion.... for example.

1.9 to 2.0 GHz improvement gives 5% roughly, but 2.5 to 2.6 Ghz is 4%...

if you are calculating from 2.66 to 3.00 gigherzt this is roughly a 12% so 9.5% is not horrid scaling but does demonstrate some BW limiting performance effects.
