Consider two different implementations of the same ISA. The characteristics of each implementation are as follows: 3. Comp2 CPI Compl Instruction Class CPI for Instruction Class for Class Class 3 4 3 B. 1 C D 1 The same compiler was used to execute a program on both machines. The number of instructions in this particular program is divided equally among the classes of instructions. Machine Comp1 runs on 3.8 GHz clock and machine Comp2 runs on 4.0 GHz clock. After the program is executed, which Computer is faster,

In the given problem statement, they have provided the two machines instructions and about their information in it. And they have given the each computers clock cycle time which is for machine computer 1 is 3.8 GHz and for the another one is 4.0 GHz.

For getting or finding the best performance of the machine out of two machines, we have the basic performance equation equation.

CPU time = (I * CPI) / R
