Price comparison
Median price per GPU per hour by billing type, with the cheapest listing under it.
| Billing | RTX 3080 | RTX 3090 Ti | Difference |
|---|---|---|---|
| On-demand | $0.15 /GPU/hr from $0.11 | -- /GPU/hr from $0.19 | |
| Reserved | -- /GPU/hr from $0.12 (3 mo) | -- /GPU/hr from $0.22 (6 mo) | |
| Spot | -- /GPU/hr from $0.06 | -- /GPU/hr from $0.10 |
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 3080 and on-demand, reserved and spot on the RTX 3090 Ti: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning. More on how we price.
