Power consumption is directly proportional to the clock speed,
not the square of the speed. It _is_ proportional to the
square of the _voltage_.
In fact, they mentioned this formula (which is way simplified):
P is proportional to C * f * V^2
where C is capacitance (which is proportional to transistor size),
f is clock speed and V is voltage.
