Price comparison
Median price per GPU per hour by billing type, with the cheapest listing under it.
| Billing | H800 | RTX 5090 | Difference |
|---|---|---|---|
| On-demand | No on-demand listings | $0.66 /GPU/hr from $0.35 | |
| Reserved | No reserved listings | $0.61 /GPU/hr from $0.21 (1 mo) | |
| Spot | No spot listings | $0.51 /GPU/hr from $0.16 |
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. Verify before provisioning. More on how we price.
