The Stockfish engine features two evaluation functions for chess, the classical
evaluation based on handcrafted terms, and the NNUE evaluation based on efficiently
-updateable neural networks. The classical evaluation runs efficiently on most 64bit
-CPU architectures, while the NNUE evaluation benefits strongly from the vector
-intrinsics available on modern CPUs (avx2 or similar).
