Consider two different processors P$1$ and P$2$ executing the same instruction set. P$1$ has a $4GHz$ clock rate and a $\frac{C}{P}$I of $1.P2$ has a $3GHz$ clock rate and a $\frac{C}{P}$I of $1\mathrm{.}5.$ Which processor has the highest performance expressed in instructions per second?

No$.$ of instruction$/$sec for $P1=$

No$.$ of instruction $\frac{?}{?}$ sec for $P2=$

Which processor has the highest performance P$1$ or P$2?$
