AlphaGo’s use of GPUs and TPUs allowed it to evaluate tens of thousands of moves per second during professional matches.

AlphaGo leveraged GPU acceleration and TPU hardware to process deep neural network computations rapidly. Convolutional layers evaluated board positions, while policy and value networks produced probability distributions over possible moves. Optimization techniques, such as batch evaluation and network pruning, reduced latency during gameplay. This allowed AlphaGo to consider hundreds of thousands of potential sequences per second while responding in real-time. Efficient inference was critical for human-competitive play. Algorithmic design and hardware co-design ensured timely decisions. Computational throughput enabled strategic depth and adaptability. Machine reasoning matched temporal constraints of live competition. Prediction and search were synchronized.
