Price comparison
Median price per GPU per hour by billing type, with the cheapest listing under it.
| Billing | RTX 4090 | RTX PRO 4500 | Difference |
|---|---|---|---|
| On-demand | $0.44 /GPU/hr from $0.32 | $0.82 /GPU/hr from $0.32 | 46% cheaper on RTX 4090 |
| Reserved | $0.52 /GPU/hr from $0.25 (24 mo) | -- /GPU/hr from $0.29 (1 mo) | |
| Spot | $0.33 /GPU/hr from $0.16 | -- /GPU/hr from $0.28 |
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 PRO 4500: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning. More on how we price.
