Pro doplneni vysvetleni treba z Anandtechu:
"Within NVIDIA’s product stack for deep learning, they have opted to divide it into two categories of products: training cards and inferencing cards. Neural network training, which typically requires FP16 performance and a whole lot of horsepower, is handled by the likes of the Tesla P100 series, the only cards in NVIDIA’s lineup with a high performance FP16 mode. Meanwhile, because inferencing can be done with less precision on a smaller scale, NVIDIA has offered the M40/M4 cards, and now the P40/P4 cards for this task."
