Price comparison
Median price per GPU per hour by billing type, with the cheapest listing under it.
| Billing | B300 | H100 | Difference |
|---|---|---|---|
| On-demand | $9.32 /GPU/hr from $6.50 | $3.63 /GPU/hr from $1.79 | 61% cheaper on H100 |
| Reserved | $5.46 /GPU/hr from $4.25 | $3.29 /GPU/hr from $1.53 (1 mo) | 40% cheaper on H100 |
| Spot | $5.52 /GPU/hr from $4.08 | $2.24 /GPU/hr from $1.29 | 59% 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.
