The kinds of GPUs that are in use in enterprise are 30-40k and require a ~10KW system. The challenge with lower power cards is that 30 1k cards are not as powerful, especially since usually you have a few of the enterprise cards in a single unit that can be joined efficiently via high bandwidth link. But even if someone else is paying the utility bill, what happens when the person you gave the card to just doesn’t run the software? Good luck getting your GPU back.
