Suppose you have a CPU with a clock speed of $4\mathrm{.}0GHz$ that requires $80W$ of power to operate. How much power would the same CPU be if the clock speed was increased to $5\mathrm{.}0GHz$ while increasing the voltage from $1\mathrm{.}0V$ to $1\mathrm{.}25V$ in order to achieve that higher clock speed? $5.$ Suppose you have a CPU that currently uses $140W$ of power while operating at a clock speed of $4\mathrm{.}3GHz$ at $1\mathrm{.}4V.$ Assuming you wanted to reduce the power used by $30W($i$.$e$.$ to $110W)$ without reducing the clock speed of that CPU, how much would you need to reduce the voltage by$?$ You should assume that the capacitive load of the CPU remains unchanged for the purposes of this problem.
