Best GPU for 70B and bigger AI models
The "B" in a model's name is how many billions of settings it has. Bigger models give better answers but need more memory: to run 70B and bigger models fully on the card (or a Mac's shared memory) you need at least 42 GB. Below is every option we track with that much memory and a verified UK price, ranked by value where there are enough real speed tests. Prices refresh every morning.
