Question: Processor A has a clock speed of 1.5 GHz and 4 classes of instructions, with CPIs of 1, 2, 3, and 4 respectively. Processor B

  1. Processor A has a clock speed of 1.5 GHz and 4 classes of instructions, with CPIs of 1, 2, 3, and 4 respectively. Processor B has a clock speed of 2.0 GHz and the same 4 classes of instructions, with CPIs of 2, 3, 4, and 5. If the number of instructions executed in a program is divided equally among the 4 classes of instructions, which processor is faster and by how much? Express your answer as ratio e.g. 2.1x faster. Hint: choose a number of instructions so you can use the classic performance equation on L1 slide 24
