Price comparison
Median price per GPU per hour by billing type, with the cheapest listing under it.
| Billing | RTX 3080 | RTX 5090 | Difference |
|---|---|---|---|
| On-demand | $0.15 /GPU/hr from $0.11 | $0.67 /GPU/hr from $0.35 | 77% cheaper on RTX 3080 |
| Reserved | -- /GPU/hr from $0.11 (3 mo) | $0.60 /GPU/hr from $0.21 (1 mo) | |
| Spot | -- /GPU/hr from $0.06 | $0.46 /GPU/hr from $0.25 |
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: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning. More on how we price.
