Just to show you how hard that wourd be, your mesuring units are extremely 
useless. Messuring processor power using megahertz is like mesurring speed of 
vehicles by messuring horsepower. You'll find big trucks with more 
horse-power that a F1 car, yet, the big truck is slower.
Frecuency of procesor only guarantees the same change in power in the same 
branch of processors, like comparing two P4, or two Athlon XP, but if you 
start comparing AMD vs Intel, that is no longer valid, and let me drop a 
different processor like a Spark, PowerPC, etc, and the comparation is very, 
very useless.
We should start comparing procesors with better mesurring units, like flop 
(floating point operations per second).
Even then, when messuring a system for something like handling calls, bus 
speed may be important, as well as network speed (don't neglect those other 
aspects). If you do transcoding of all the calls, then you'll need a lot of 
processor ;)
