How many nodes can pro servers can compute during 15s?
Greetings!
Stockfish evaluates some positions faster than others, so node count during a 15 second calculation can vary based on the position you’re analyzing.
I did a little test and performed a 15 second analysis on the positions Stockfish uses for it’s internal benchmark – here’s the results:
