Price comparison
Median price per GPU per hour by billing type, with the cheapest listing under it.
| Billing | RTX 3090 Ti | RTX 4000 SFF Ada | Difference |
|---|---|---|---|
| On-demand | $0.22 /GPU/hr from $0.19 | -- /GPU/hr from $0.42 | |
| Reserved | -- /GPU/hr from $0.16 (48 mo) | No reserved listings | |
| Spot | -- /GPU/hr from $0.10 | 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 RTX 3090 Ti and on-demand on the RTX 4000 SFF Ada: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning.
