You can test Voltas on AWS, the prices are very acceptable. I had problems getting good convergence with fp16 training, even taking into account all the tricks in NVIDIA's "mixed precision learning" document and using the respective NVIDIA-caffe branches. It worked for the policy network, but not for the value network. You only get 110 TFLOPS when using the mixed precision fp16 into fp32 accumulator matrix multipliers from the Tensor Cores, otherwise it's not so different from a 1080 Ti in speed. It has a lot of cores, but the clock-speed is much lower. I also had the impression that using the Tensor Cores disables the Winograd transform, perhaps due to accuracy issues? So you lose a factor ~3 in speedup.
