Houdini 6 makes better use of multiple threads and will be particularly strong on hardware with many cores.
Every aspect of the engine has been thoroughly reviewed and refined: evaluation, search, time management and table base usage. This playing strength increase means that Houdini 6 is stronger than Houdini 5 using twice the time or in other words, upgrading to Houdini 6 is like doubling the computational power of your computer for chess. Houdini 6 continues the impressive surge made by its predecessor by adding another 50 to 60 Elo in strength, to become once again the strongest engine that money can buy. Computer engines have made amazing progress these last years. Yes! One can say Houdini 6 is the “world champion” of all of the world’s chess engines, rated so far above 3000 that no human has any chance to beat it.
