Интересно, почему на макбуках с Intel оптимизация дала очень малый прирост, когда на макпро с интелом же оптимизация дала прирост сравнимый с разницей между Intel и M1 на макбуках. Выглядит подозрительно.
В оригинальной новости приводили характеристики, теста, которые намекают на использование GPU AMD для ускорения вычислений. Но для этого, видимо, придется уйти от собственно tensorflow.
Testing conducted by Apple in October and November 2020 using a preproduction 13-inch MacBook Pro system with Apple M1 chip, 16GB of RAM, and 256GB SSD, as well as a production 1.7GHz quad-core Intel Core i7-based 13-inch MacBook Pro system with Intel Iris Plus Graphics 645, 16GB of RAM, and 2TB SSD. Tested with prerelease macOS Big Sur, TensorFlow 2.3, prerelease TensorFlow 2.4, ResNet50V2 with fine-tuning, CycleGAN, Style Transfer, MobileNetV3, and DenseNet121. Performance tests are conducted using specific computer systems and reflect the approximate performance of MacBook Pro.
