This is an interesting point. Which makes me wonder: is 3.5 GIPS a realistic measure of nowadays commodity CPUs? Because those figures seem to describe CPU clock frequency instead, and it turns out that most instructions take more that 1 tick to complete execution; on the other hand, instruction pipelining and other optimization strategies may lower the ticks-per-instruction average number closer to (or even beyond) 1. Can anyone more informed than me shed some light on this? |

Compare pmc data for instructions retired .vs processor unhalted.
