Processor Clock Rate CPI Instructions

P1 4 GHz 0.9 5.0E9

P2 3 GHz 0.75 1.0E9

According to these values; when we calculate TP1 and TP2;

TP1 = 0.9 x 5 x 109 / 4 x 109 = 1.125 seconds

TP2 = 0.75 x 109 / 3 x 109 = 0.25 seconds

Thus, in this case P2 has better performance because of its lower CPI and number of instructions.

A computer with the largest clock rate does not mean it will have the largest performance. By overclocking you may be able to reach the maximum capacity of a CPU, but perhaps buying an upgraded CPU with more processing power will out do the former computer minus the overclocking method to the latter upgraded PC.
