Section $1\mathrm{.}10$ cities as a pitfall the ultilization of a subset of the performance equation as a performance metric. To illustrate this, consider the following two processors. P$1$ has a clock rate of $4$ GHz$,$ average CPI of $0\mathrm{.}9,$ and requires the execution of $5\mathrm{.}0$E$9$ instructions. P$2$ has a clock rate of $3$ GHz$,$ an average CPI of $0\mathrm{.}75,$ and requires the execution of $1\mathrm{.}0$E$9$ instructions.

$1\mathrm{.}12\mathrm{.}1$ One usual fallacy is to consider the computer with the largest clock rate as having the largest performance. Check if this is true for P$1$ and P$2.$
