Price comparison
Median price per GPU per hour by billing type, with the cheapest listing under it.
| Billing | B300 | RTX 5070 | Difference |
|---|---|---|---|
| On-demand | $8.25 /GPU/hr from $4.99 | $0.19 /GPU/hr from $0.13 | 98% cheaper on RTX 5070 |
| Reserved | $6.25 /GPU/hr from $4.25 | -- /GPU/hr from $0.12 (1 mo) | |
| Spot | $5.20 /GPU/hr from $2.99 | -- /GPU/hr from $0.08 |
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. No median for reserved and spot on the RTX 5070: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning. More on how we price.
