It is a vastly improved and 100-130 Elo stronger version of this classical program. The gain in playing strength offers real practical advantages: Komodo Dragon 3 takes only about a quarter of the time to play or analyze at the same level as Dragon 2! The large Elo increase is due to a new net structure for NNUE with a corresponding new net, as well as various optimizations and improvements in the search.
