Price comparison
Median price per GPU per hour by billing type, with the cheapest listing under it.
| Billing | B300 | H100 | Difference |
|---|---|---|---|
| On-demand | $8.82 /GPU/hr from $4.99 | $3.49 /GPU/hr from $1.71 | 60% cheaper on H100 |
| Reserved | $5.97 /GPU/hr from $4.25 | $3.26 /GPU/hr from $1.53 (1 mo) | 45% cheaper on H100 |
| Spot | $5.07 /GPU/hr from $4.08 | $1.94 /GPU/hr from $0.67 | 62% cheaper on H100 |
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.
