The K80s are serious compute (for example, they include ECC memory), but don't compare to more modern gaming kit. Also, each VM gets only one of the two K80 GPUs. This is the same over on Azure, GCE, and ECS.

Definitely should be analyzed. I think this is early days; different Notebooks can be created and shared to focus on a particular compute space, and each individual user gets to choose which they run in their (singular) VM.
