I would say exponentially if this is accurate and I'm understanding it correctly:

The switching power dissipated by a chip using static CMOS gates is C·V²·f, where C is the capacitance being switched per clock cycle, V is voltage, and f is the switching frequency,

Of course, the caveat:

The formula is not exact however, as many modern chips are not implemented using 100% CMOS, but also uses pseudo nMOS gates, domino logic etc. Moreover, there is also a static leakage current, which has become more and more accentuated as feature sizes have become smaller (below 90 nanometres) and threshold levels lower.

Looks like a good answer to me.
