NPS as a measure of chess strength is useless. I can make an evaluation that just counts the material on the board and does one million NPS. A 200K NPS smart evaluation will clobberize it. Forget NPS as a measure of chess strength. The only usefulness of NPS is to measure a chess program against itself. People don't even have the same meaning for the term from program to program. So if I run a program on hardware X and get 500K NPS and I run the same program on hardware Y and get 1500 NPS, then I know that the program runs 3x as fast on hardware Y. That is all. I don't know anything about how strong it is in relation to another program or even if it will play a lot better. I only know how much faster it runs, relative to itself.
