You can run FP16 calculations on 1080 Ti, and you get a marginal speed up over FP32. Of course, 1080 Ti does not have Tensor Cores, so you don't get the level of speed up that you do with Titan V / V100. The new 2080 Ti have Tensor Cores. I will be posting numbers when I get my hands on one (should be very soon).
