Question $1$

One computer, named Computer I, has a $4GHz$ clock, which takes $25$ seconds to run a program. As a Computer Architecture Designer, you are required by your manager to design a computer, Computer II$,$ which will only run this program in $15$ seconds $($Note that it is possible for you to have a significant increase in the clock rate. This increase will make the Computer II to require $1\mathrm{.}5$ times as many clock cycles as Computer I for this program$).$ As a Computer Architecture Designer, please determine the clock rate of Computer II$.$

Question $2$

Computer I, has a clock cycle time of $60$dps and a CPI of $1\mathrm{.}5$ for some program, whereas Computer II has a CPI of $3$ for the same program with a clock cycle time of $200$ ps$.$ Assume that these two implementations use the same ISA. Please carry out a performance analysis which computer is slower for this program and by how much?
