Price comparison
Median price per GPU per hour by billing type, with the cheapest listing under it.
| Billing | H800 | RTX 6000 Ada | Difference |
|---|---|---|---|
| On-demand | No on-demand listings | $0.86 /GPU/hr from $0.54 | |
| Reserved | No reserved listings | -- /GPU/hr from $0.54 (1 mo) | |
| Spot | No spot listings | -- /GPU/hr from $0.27 |
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 RTX 6000 Ada: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning. More on how we price.
