It is obvious that most chess softwares have different algorithms unless it is a
clone. As far as the hardware differences, nodes per seconds is not pure
nonsense. Now here is the final logical conclusion, is you take Chess Junior 5.0
and install it inside of a Pentium III 850 Mhz which of course it will produce a
bigger count of nodes per second, than if you install the latest version of
Fritz 6a inside of a Pentium II 450 Mhz, you will expect Junior to win a least
60% of the games.

PS: In my previous example the softwares and the hardwares were differents, but
the difference in speed made a big difference.
