Price comparison
Median price per GPU per hour by billing type, with the cheapest listing under it.
| Billing | A4000 | RTX 3080 | Difference |
|---|---|---|---|
| On-demand | $0.19 /GPU/hr from $0.07 | $0.12 /GPU/hr from $0.08 | 35% cheaper on RTX 3080 |
| Reserved | $0.18 /GPU/hr from $0.06 (3 mo) | -- /GPU/hr from $0.10 (1 mo) | |
| Spot | -- /GPU/hr from $0.05 | -- /GPU/hr from $0.04 |
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 spot on the A4000 and reserved and spot on the RTX 3080: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning. More on how we price.
