Price comparison
Median price per GPU per hour by billing type, with the cheapest listing under it.
| Billing | RTX A2000 | B300 | Difference |
|---|---|---|---|
| On-demand | Sold out | $8.99 /GPU/hr from $4.99 | |
| Reserved | No reserved listings | $5.46 /GPU/hr from $4.25 | |
| Spot | No spot listings | $6.17 /GPU/hr from $4.08 |
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.
