When I was mining with a bunch of RTX 3080s and RTX 3090s, the electricity cost (admittedly) was about $20/month per card. Running a 70B model takes 3-4 cards. Assuming you're pushing these cards to their extreme max, it's going to be $80/mo. Then again, ChatGPT is pretty awesome, and is likely running more than a 70B model (or I think I heard it was running an ensemble of models), so there's at least a ballpark.
- sodality2 3y agoBatched inference makes these calculations hard - roughly takes the same amount of power and time for one inference vs 30 (as i understand it)
- Sebb767 3y agoDatacenters probably do not pay retail rates on electricity, so they might actually run quite a bit cheaper (or more expensive if they use highly available power, but this seems like overkill for pure compute power).
- 015a 3y agoSure, but everything else about a data center is more expensive (real estate, operations people, networking, equipment). There's a reason AWS is so expensive.
