Alpha Zero would not be competitive in its original implementation. It's neural net is too small (this is why it only took 4 hours to train it, since it stopped learning after 4 hours). Stockfish 14 just doubled its network size from Stockfish 13.

Stockfish 8 actually won games against Alpha Zero. But Stockfish 11 (which is still classical evaluation engine with no neural net support) totally decimates Stockfish 8, and Stockfish 13 (which uses neural net) totally decimates Stockfish 11. Stockfish 14 just got 30 elo points stronger than 13.

As it stands now, Stockfish 14 is the strongest chess entity humanity has ever seen.
