Price comparison
Median price per GPU per hour by billing type, with the cheapest listing under it.
| Billing | B300 | RTX 2000 Ada | Difference |
|---|---|---|---|
| On-demand | $7.87 /GPU/hr from $6.50 | $0.24 /GPU/hr from $0.12 | 33x more expensive on B300 |

| Spot | $5.85 /GPU/hr from $4.30 | 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.
