p2.xlarge comes with an NVIDIA Tesla K80 GPU for $0.90/hr, but this is now an "old" GPU and the RTX Quadro 6000 should have much higher performance (but I was unable to find any machine learning benchmarks).
p3.2xlarge has NVIDIA Tesla V100 GPU which is NVIDIA's most recent deep learning GPU, but it's $3.06/hr.
That said, AWS is among the most expensive providers if you just need a deep learning GPU (but obviously AWS offers a lot of other useful things). For example, OVH Public Cloud has Tesla V100 for $2.66/hr. And comparable NVIDIA GPUs that are not "datacenter-grade" should be even cheaper; AWS, GCP, Azure, etc. are unable to offer them because of contracts when they buy e.g. the Tesla V100.
The K80s are super outdated now. Google used to offer them for free for 12hrs a day on their Colab platform, but they upgraded them to using the Tesla T4s. Note you can get a K80 on GCP (unreserved) for $.45/hr.
K80 is the crappiest cards I've used last year. For sure it was a good choice 2 years ago, but now you are better to upgrade as any new desktop card is better than K80

This is a good deal.
