"Overclocked" frequency and Power dissipation

What is the relationship between the "Overclocked" frequency on a CPU and its power dissipation? Thx

CPU's are digital circuits and the old technology was to built those circuits in totem-pole configuration when one segment is on and the other off. But on transition there is a short time when both segments are conducting current and this is doing work (read, producing heat). When you overclock, two possibilities, one the clock is too fast for the matrix to respond and do something useful, two the whole package is not build to release the additional heat produced, so bye,bye CPU!

Roughly linearly proportionate. For example, 10% increase in clock speed ~=

10% increase in power dissipation.

Any mathematical equations??? Thanks Jack

What are you looking for, a physical motivation for the relationship or a practical rule of thumb? In other words, what do you need the equation for?

Very roughly;^), dependant on linearity of the package to dissipate the additional linearly produced heat. (Thermodynamics, enthropy, refrigeration and other technical vermin) Note: "Don't overclock unless you know what you are doing!"
