Price comparison
Median price per GPU per hour by billing type, with the cheapest listing under it.
| Billing | A40 | V100S | Difference |
|---|---|---|---|
| On-demand | $0.65 /GPU/hr from $0.40 | -- /GPU/hr from $0.88 | |
| Reserved | -- /GPU/hr from $0.61 (24 mo) | No reserved listings | |
| Spot | -- /GPU/hr from $0.27 | 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 reserved and spot on the A40 and on-demand on the V100S: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning. More on how we price.
