Price comparison
Median price per GPU per hour by billing type, with the cheapest listing under it.
| Billing | RTX A6000 | GB300 | Difference |
|---|---|---|---|
| On-demand | $0.56 /GPU/hr from $0.35 | -- /GPU/hr from $18.00 | |
| Reserved | $0.48 /GPU/hr from $0.35 | On request | |
| Spot | $0.40 /GPU/hr from $0.20 | Sold out |
Heads up: A provider's own page may quote a different figure, for example on tax, region or a promotion. A monthly-only plan shows a derived hourly rate. Medians are across providers, one vote each, so a large catalog does not outweigh a small one. No median for on-demand on the GB300: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning. More on how we price.
