WebAug 8, 2014 · "CPI" is a throughput measure of how many instructions are completed (on average) for a given number of clocks. A CPU that can complete, on average, 2 instructions per cycle (a CPI of 0.5) may have a 20 stage pipeline, which inevitably causes a 20 cycle latency between an instruction fetch to the completion of that instruction.
