There are quite a few benchmarks and comparisons online, I work for GCP so I don't want to give a biased answer.
Also, K80s are pretty old these days, though this makes them much cheaper than P100s and V100s. Comparing all of them from a price/perf standpoint (especially with TPUs in the mix) can get tricky because it's different for every use case.
