Where did you get that the 1080ti is 60% of the performance of the p100? It is slightly higher performance than the p100, but rated with a lower mtbf. Of course

Where did you get that the 1080ti is 60% of the performance of the p100? It is slightly higher performance than the p100, but rated with a lower mtbf. Of course, you end up with many crippled features, like RDMA and dynamic parallelism, which most people probably don't need anyways.
- jamesblonde 9y agoDeep learning training is basically 2 phases: the forward pass and the backwards pass (backpropagation). There are no loops. As such, most DL training is memory bound. Memory bandwidth of 1080TI is 484.4 GB/s Memory bandwidth of p100 is 720.9 GB/s Memory bandwidth of v100 is 900.1 GB/s
- shaklee3 9y agoFor applications that are not memory bound, the 1080ti is better. Also, if we are talking about deep learning, inference can be handled with lower precision. The p100 does not have int8 support and hardware, but the 1080ti does. So presumably for the same memory bandwidth you get twice as much data.
