Price comparison
Median price per GPU per hour by billing type, with the cheapest listing under it.
| Billing | A4000 | RTX A6000 | Difference |
|---|---|---|---|
| On-demand | $0.23 /GPU/hr from $0.12 | $0.59 /GPU/hr from $0.35 | 61% cheaper on A4000 |
| Reserved | $0.25 /GPU/hr from $0.11 | $0.64 /GPU/hr from $0.35 | 61% cheaper on A4000 |
| Spot | No spot listings | $0.47 /GPU/hr from $0.40 |
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.
