>Second, the mechanism should be efficient. Here, efficiency refers to the ratio between power reduction and performance loss. An ideal mechanism results in a power vs. performance curve that is linear and crosses both axes at 0. In other words, if the power modulation mechanism results in a 10% performance loss while operating, it would also provide a 10% reduction in power consumption. Note an ideal relationship is only possible if frequency is the only variable.< What a line of bull! AMD could implement clock throttling as an offshoot of PowerNow! Such an implementation would drop the voltage along with the frequency, resulting in more than a 10% drop in power consumption for a 10% drop in performance. In view of this potential, how can a linear relationship be considered ideal?
