Price comparison
Median price per GPU per hour by billing type, with the cheapest listing under it.
| Billing | B300 | RTX PRO 4500 | Difference |
|---|---|---|---|
| On-demand | $8.62 /GPU/hr from $4.99 | $0.92 /GPU/hr from $0.72 | 89% cheaper on RTX PRO 4500 |

| Spot | $5.99 /GPU/hr from $4.08 | No spot listings |
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. Verify before provisioning. More on how we price.
