Price comparison
Median price per GPU per hour by billing type, with the cheapest listing under it.
| Billing | L40 | RTX 3090 Ti | Difference |
|---|---|---|---|
| On-demand | $1.00 /GPU/hr from $0.46 | $0.27 /GPU/hr from $0.19 | 73% cheaper on RTX 3090 Ti |
| Reserved | -- /GPU/hr from $0.70 | -- /GPU/hr from $0.17 (48 mo) | |
| Spot | $0.79 /GPU/hr from $0.40 | -- /GPU/hr from $0.10 |
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 L40 and reserved and spot on the RTX 3090 Ti: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning.
