Price comparison
Median price per GPU per hour by billing type, with the cheapest listing under it.
| Billing | H100 | RTX 3070 | Difference |
|---|---|---|---|
| On-demand | $3.38 /GPU/hr from $1.30 | $0.11 /GPU/hr from $0.08 | 97% cheaper on RTX 3070 |
| Reserved | $3.12 /GPU/hr from $1.53 (1 mo) | -- /GPU/hr from $0.08 (1 mo) | |
| Spot | $2.00 /GPU/hr from $0.36 | -- /GPU/hr from $0.04 |
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 3070: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning. More on how we price.
