Price comparison
Median price per GPU per hour by billing type, with the cheapest listing under it.
| Billing | B300 | RTX 3060 | Difference |
|---|---|---|---|
| On-demand | $8.25 /GPU/hr from $4.99 | -- /GPU/hr from $0.05 | |
| Reserved | $6.50 /GPU/hr from $4.25 | -- /GPU/hr from $0.06 (1 mo) | |
| Spot | $4.87 /GPU/hr from $2.99 | -- /GPU/hr from $0.03 |
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 on-demand, reserved and spot on the RTX 3060: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning. More on how we price.
