Price comparison
Median price per GPU per hour by billing type, with the cheapest listing under it.
| Billing | A40 | RTX 6000 Ada | Difference |
|---|---|---|---|
| On-demand | $1.05 /GPU/hr from $0.65 | $0.96 /GPU/hr from $0.48 | 8% cheaper on RTX 6000 Ada |
| Reserved | -- /GPU/hr from $0.61 (24 mo) | -- /GPU/hr from $1.04 (12 mo) | |
| Spot | -- /GPU/hr from $0.33 | -- /GPU/hr from $0.34 |
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 reserved and spot on the RTX 6000 Ada: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning.
