Suppose we have two implementations of the same instruction set architecture. Computer A has a clock cycle time of 250 ps and a CPI of 2.0 for some program, and computer B has a clock cycle time of 500 ps and a CPI of 1.2 for the same program. Which computer is faster for this program and by how much? Suppose we have two implementations of the same instruction sel architecture Machine 1 has a clock rate of 500 MHz and takes an average of 2.0 clock eydes per instruction for a program. Machine 2 has a clock rate of IGHz and a CPI of 4 for a program. Then
