 Problem 4. Suppose you are comparing the performance of two computers:

Problem 4. Suppose you are comparing the performance of two computers: A and B A has a clock frequency of 2.1GHz and B has a clock frequency of 4 Ghz Ais a RISC architecture with an average CPI for an integer benchmark of 3 and B is an x86 (CISC) architecture with an average CPI for the same benchmark of 8 Execution time = Number of instructions x CPI x clock cycle time Assuming the size of the benchmark code in B is 20% smaller than benchmark code in A, what clock frequency does B need to run at to have the same execution time performance as A
