A ton of CPU has gone into Stockfish, if only for their distributed computing project fishnet: http://tests.stockfishchess.org/tests http://tests.stockfishchess

- gwern 9y agoTo be a little more precise: Stockfish has used >5,667,382 CPU-hours (5.6 million CPU-hours) adding up just the participants who contributed >10,000 CPU-hours according to https://github.com/mcostalba/Stockfish/blob/master/Top%20CPU%20Contributors.txt https://github.com/mcostalba/Stockfish/blob/master/Top%20CPU...
- nojvek 9y agoYes but that's training time. At runtime AlphaZero got magnitudes more computation power than stockfish. A more fair comparison would be use as much computation needed for training but for runtime, use equal wattage hardware. E.g 20W of cpu in mobile phone running stockfish to 20W of GPU in nvidia TX2 running AlphaZero to 20W human brain.
