It actually goes exponentially with voltage and temperature. This means scaling up the voltage for higher frequency and in turn heating up the CPU increases leakage by factors, which makes the original power saving equation somehow dubious.

Would you mind clarifying what do you mean by "original power saving equation" and "dubious"?
