Price comparison
Median price per GPU per hour by billing type, with the cheapest listing under it.
| Billing | B300 | K80 | Difference |
|---|---|---|---|
| On-demand | $8.50 /GPU/hr from $4.99 | -- /GPU/hr from $0.90 | |
| Reserved | $6.25 /GPU/hr from $4.25 | -- /GPU/hr from $0.04 (24 mo) | |
| Spot | $5.07 /GPU/hr from $2.99 | No spot listings |
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 on-demand and reserved on the K80: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning. More on how we price.
