Technically it is. Eric Demers posted this



So it sounds like cache can cause performance to scale greater than linearly

I stand corrected, but this only applies to Crossfire scaling.

So it goes like this: If clockspeed(or amount of cards, processors, memory etc.) increases by 100%, performance can't increase by more than 100% UNLESS the internal efficiency of the chip increases aswell (In this case the additional cache increased the internal efficiency of crossfire, thus the +100% increase in performance).
