instructions per cycle completed being much higher than 1 and is responsible for much of the speed improvements in subsequent CPU generations.

Calculation of IPC

The calculation of IPC is done through running a set piece of code, calculating the number of machine-level instructions required to complete it, then using high-performance timers to calculate the number of clock cycles required to complete it on the actual hardware. The final result comes from dividing the number of instructions by the number of CPU clock cycles.
