Nvidia GPU microarchitecture and pipeline organization documentation

Is there any documentation related to Nvidia’s GPUs microarchitecture and pipeline organization? Precisely I’m looking for gtx 1070 microarch docs.

I’m not suggesting that is a complete answer to your question. It represents approximately the extent of what is formally documented by NVIDIA. GPU microarchitecture and pipeline organization is also sometimes inspected by 3rd party papers that do microbenchmarking. You may wish to try some google searches.
