How the CPU step-down current will change

Q: At CPU rated operating frequency, I reduce its operating voltage, then the current flow through the CPU is increased or decreased? Some people think that the electric current will increase because his power is basically unchanged. But some people think it will be lowered, and he makes the CPU equivalent to a resistor. But I don't think it's going to be that simple. I would like to ask you to express your views. and is step-down overclocking will damage the CPU?

A: The current will definitely decrease, and the power consumption will decrease. But with the side effects of the internal CMOS tube due to voltage reduction, the reliability of the work is reduced, which means that the CPU will be unstable, power and CPU stability is a pair of contradictions. Now High-performance CPU current maximum can reach 60A, and the voltage can be as low as 1V, the purpose is to reduce the function, otherwise the thermal design will be very difficult. And the cooling is bad, the stability of the CPU will be reduced. Buck is hard to overclocking, unless the CPU is doing a very large margin. Generally it is boost (make the CPU work more reliable), and then overclocking (make the CPU unstable), and then find the balance point. Buck, generally does not damage the CPU boost, basically will damage the CPU more or less.
