lm123

Why does the power increase faster than linearly with respect to voltage? Is this a direct effect of physical laws or does it have to do with processor design?

mm

@lm123 this is because power is equal to voltage squared divided by resistance (P = V^2/R). So assuming resistance stays the same, if you double the voltage, you quadruple the power.

I understand that higher frequencies equate to higher power, as evident with light waves. But how does frequency of a clock relate to core voltage?

@DudaK It's because of the capacitance of MOSFET-based circuits. By increasing the voltage, the capacitors are able to charge and discharge faster, which allows for faster operation of the circuit and higher clock frequencies. source
