FP16 is supported but at a low rate. So performance won’t be interesting. The driver version you have should be fine. I would recommend using CUDA 8.0.61 (CUDA 8 GA2) which is what is currently publicly available.
The only GPUs with full-rate FP16 performance are Tesla P100, Quadro GP100, and Jetson TX1/TX2.
All GPUs with compute capability 6.1 (e.g. GTX 1050, 1060, 1070, 1080, Pascal Titan X, Titan Xp, Tesla P40, etc.) have low-rate FP16 performance. It’s not the fast path on these GPUs. All of these GPUs should support “full rate” INT8 performance, however.
