"Undervolting reduces the voltage and hence the power and temperature at the same performance level. "
That is not true, Laptop CPUs are designed to use lower voltages primarily to save on power in the interests of Battery life, the performance is also lowered.
Perhaps people should mug up on some Semiconductor Physics.
I just use snake oil paint on the "Intel CORE i7" label, changing the i7 to i9.
People always think they can get something for nothing, hence the proliferation of Optimising Apps like the one mentioned.
All this is off topic for the OP.
I am a physicist. The performance has nothing to do with semiconductor physics. It has to do with how the processors are throttled on power, current and temperature - not voltage - and Ohm's law (including the power relationship).
It is not off topic in the sense undervolting can be used to reduce temperatures and was already brought up in that contest in this topic. I am responding to try and clear up some misconceptions. You yourself responded and so are also responsible for perpetuating the discussion btw.
