Price comparison
Median price per GPU per hour by billing type, with the cheapest listing under it.
| Billing | MI455X | GB200 | Difference |
|---|---|---|---|
| On-demand | No on-demand listings | $16.00 /GPU/hr from $10.50 | |
| Reserved | No reserved listings | -- /GPU/hr from $10.58 | |
| Spot | No spot listings | -- /GPU/hr from $27.04 |
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 GB200: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning. More on how we price.
