Price comparison
Median price per GPU per hour by billing type, with the cheapest listing under it.
| Billing | MI350X | GB300 | Difference |
|---|---|---|---|
| On-demand | No on-demand listings | -- /GPU/hr from $18.00 | |
| Reserved | -- /GPU/hr from $4.76 (12 mo) | On request | |
| Spot | -- /GPU/hr from $2.46 | 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 reserved and spot on the MI350X and on-demand on the GB300: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning.
