The neural network of Stockfish NNUE consists of four layers, W1 through W4. The input layer W1 is heavily overparametrized, feeding in the [[Board Representation|board representation]] for various king configurations.

where only a fraction of its neurons need to be recalculated. The remaining three layers with 256x2x32-32x2x256, 32x32-and 32x1 neurons weights are computational less expensive, best calculated using appropriate [[SIMD and SWAR Techniques|SIMD instructions]] like [[AVX2]] on [[x86-64]], or if available, [[AVX-512]].
