Price comparison
Median price per GPU per hour by billing type, with the cheapest listing under it.
| Billing | RTX 3080 Ti | RTX 5090 | Difference |
|---|---|---|---|
| On-demand | $0.18 /GPU/hr from $0.13 | $0.67 /GPU/hr from $0.35 | 73% cheaper on RTX 3080 Ti |
| Reserved | -- /GPU/hr from $0.12 (48 mo) | $0.59 /GPU/hr from $0.21 (1 mo) | |
| Spot | -- /GPU/hr from $0.08 | $0.48 /GPU/hr from $0.20 |
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 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.
