There are only smart and stupid engine.
If you start from the same playing strenght(let say 2700 elo) and you double the number of nodes of smart new stockfish you probably get the same improvement that you get from multiplying the number of nodes of stupid engine like Fritz or Hiarcs or my own engine by 10(do not know if it is 7 or 13 but the idea is clear).
I wonder if people test chess engines in order to find nodes equivalence function meaning
n nodes per move of engine x is the same playing strength as f(n) nodes of engine y.
A big problem with using node counts is that engines count them very differently.
Some engines do not count singular move extensions and some do
Some don't count hash nodes and some do
some don't count qnodes and some do
The meaning of a node for LC0 is very different from a node for Stockfish, and depth also has completely different meanings.
I think a better way to compare strength between different engines would be to use time handicaps, which are linear multiples of the stronger engine time.
