Price comparison
Median price per GPU per hour by billing type, with the cheapest listing under it.
| Billing | A4000 | RTX PRO 4000 SFF | Difference |
|---|---|---|---|
| On-demand | $0.22 /GPU/hr from $0.10 | -- /GPU/hr from $0.38 | |
| Reserved | $0.20 /GPU/hr from $0.11 | No reserved 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 on the RTX PRO 4000 SFF: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning. More on how we price.
