The node rate is not a good parameter for comparison. Engines of very similar
strengths (within +/- 50 Elo) and depths can have differences of their node
rates of up to 1:10. For example, King or Hiarcs have only ~1/8 of the node rate
of Fritz or Junior, on the same computer.

Depths are not a good parameter for comparison anymore either, because the
engines are so differently designed. Hiarcs 9 at depth 18 would be much stronger
than Shredder 9 at depth 18.
