Price comparison
Median price per GPU per hour by billing type, with the cheapest listing under it.
| Billing | RTX A6000 | RTX PRO 4500 | Difference |
|---|---|---|---|
| On-demand | $0.63 /GPU/hr from $0.35 | $0.92 /GPU/hr from $0.72 | 32% cheaper on RTX A6000 |
| Reserved | $0.54 /GPU/hr from $0.35 | On request | |
| Spot | -- /GPU/hr from $0.40 | 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. No median for spot on the RTX A6000: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning. More on how we price.
