Price comparison
Median price per GPU per hour by billing type, with the cheapest listing under it.
| Billing | B300 | RTX 6000 Ada | Difference |
|---|---|---|---|
| On-demand | $8.62 /GPU/hr from $4.99 | $1.07 /GPU/hr from $0.65 | 88% cheaper on RTX 6000 Ada |
| Reserved | $5.47 /GPU/hr from $4.25 | -- /GPU/hr from $1.04 (12 mo) | |
| Spot | $5.99 /GPU/hr from $4.08 | Sold out |
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 on the RTX 6000 Ada: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning. More on how we price.
