The NPS is not the a true scientific measure of Knowing why a certain program benefit more than another from the gain in processors speed. For instance, if you provide Nimzo 8 to play a game by using 1 Minute per moves and at the same time you provide Junior 6 also 1 minute per move. You might have this escenario: 1. Let say that after one minute Nimzo 8 was able to reach XXXXXX NPS by using the Celeron 333 MHz but was not able to find the best move within that horizon, whereas Junior 6 by reaching XXXXXX NPS was able to find a better move. Now when you increase the speed of the processor to a higher level (K6-2 500 MHz) Nimzo 8 is now getting closer to zero in, where it could find a better move provided the same amount of time of 1 minute per move, whereas Junior 6 is still providing almost the same evaluation. Finally, when you increase the speed of the processor to a minimum of 800 MHz, Junior 6 is of course calculating a higher number of NPS, but is not improving the evaluation too significant as compared to Nimzo 8 when is finally reaching is peak.
