The Xbox One's Insides Have Changed A Little Bit Since E3 - GPU clockspeed upped

The increase in power and heat would be insignificant, GCN scales in clockspeed very well, topping out at around 1ghz-1.2ghz.
Besides increasing clock speed by 6.6% isn't going to cause a linear increase in heat and power consumption, that occurs with voltage not clockspeed increases.

In simple terms, if you want higher speeds, you need to provide more current per time unit to the transistors. Simplified, you want 6% higher speed, you need 6% more current (which is done by increasing the driving force, the voltage). Now if you looked into your old physics book, you would find that the heat to dissipate over your resistors goes like P = I^2 * R. So contrary of what you think, heat dissipation "goes worse" with clock rate increase. AMD stuff had a tendency to go through the roof rather early (compared to Intel chips) at some clock rate. This was improved and AMD can go around 1GHz without excessive heat production. Again the key word here is "excessive" (check a 7970 for heat dissipation), the 53MHz clock rate increase does increase the heat output noticably.

Rubbish.
You don't need to increase the current (voltage) to increase clock speeds, have you learnt nothing about overclocking on the PC? Hint: People have been doing it for decades, even reducing voltages and increasing clock speeds and thus reducing heat and power consumption.

No offense, but I'll take the proof that is decades worth of overclocking over your opinion.
