I never mentioned anything about multipliers, nor do we have the option to play with multipliers on GPU's.
My point still stands, when you raise voltage, heat and power consumption increases exponentially. (I.E. The increase is the square of the voltage in a linear circuit.)
If you increase clockspeed and not the voltage, the increase in heat and power consumption isn't going to be an exponential increase, nor do you *have* to increase the voltage to run at a higher clock speed. (Untill you hit a wall and need more voltage, that is.) - Again, decades worth of proof via overclockers is available for you to peruse via google.
Also, nVidia moved away from having the shader clocks untied from the core clock some time ago.

I misundestood then... sorry.
I agree with you in that explanation... but we don't know if the voltage was increase or not to add these 53Mhz... in any case I think MS is playing safe because they had made tests with 900Mhz,1000Mhz, etc.
