  Stockfish is the unchallenged best CPU engine right now (it's most probably the best engine, period, as well). This applies regardless of the hardware you have, as long as it's a fair comparison - i.e. you run all your competing CPU engines on the same hardware.
  
  Choose the [latest version](https://abrok.eu/stockfish/) of Stockfish, or if you prefer, choose the latest stable release ([v14.1](https://stockfishchess.org/download/)).
