Practice objective / multiple choice question 23 from the 2018 Gce Model Questions Vol1 Computer Studies examination.
Two CPUs are to be compared for a program consisting of \(10^{9}\) instructions with the following instruction mix: 40 % of the instructions are class A, 35 % are class B and 25 % are class C. CPU 1: clock rate \(2.5\) GHz; CPI values - class A: 1.0, class B: 2.0, class C: 3.0. CPU 2: clock rate \(3.0\) GHz; CPI values - class A: 1.2, class B: 1.8, class C: 2.5.
