Are there benchmarks for K80 vs v100?

I am curious to learn about benchmarking old GPUs to new ones. How does v100 compare to the old K80s? On say, cifar10, imagenet and mini-imagenet using some resnet (e.g. resnet18)

K80s get absolutely smoked by the V100, even the 2080 Ti beats them handily. K80 is about the same speed as a GTX 1080.
