You're thinking about the Shannon's theorem. Here it is about knowing what operations the CPU is performing/looping on. This frequency is not related directly to the frequency at which the CPU operates: it's related to the frequency at which the plates of the capacitor oscillates (which is related to the frequency at which the CPU draws power and so operates...).
