Calculate Power Consumption of CPU

An increase in processor operating frequency not only increases system performance,
but also increases the processor power dissipation. The relationship between
frequency and power is generalized in the following equation: P = CV2F (where
P = power, C = capacitance, V = voltage, F = frequency). From this equation, it is
evident that power increases linearly with frequency and with the square of voltage.

 

But where to find capacitance for AMD Cpu's?

when you know power voltage and frequnci then you can calculate C.

for example 65W = C * 1.3^2V * 2.6GHz give 14.7nF but this is just theoretical because i think C vary from chip to chip thus TDP vary too.
