3. Suppose you have a CPU with a clock speed of 4.0 GHz that requires 100 W of power to operate. How much power would the same CPU be if the clock speed was increased to 5.0 GHz while increasing the voltage from 1.2 V to 1.5 V in order to achieve that higher clock speed? 4. Suppose you have a CPU that currently uses 125 W of power while operating at a clock speed of 3.8 GHz at 1.4 V. Assuming you wanted to reduce the power used by 20 W (i.e. to 105 W) without reducing the clock speed of that CPU, how much would you need to reduce the voltage by? You can assume that the capacitive load of the CPU remains unchanged for the purposes of this problem.
