Price comparison
Median price per GPU per hour by billing type, with the cheapest listing under it.
| Billing | Radeon RX 7900 XTX | GTX 1660 Super | Difference |
|---|---|---|---|
| On-demand | -- /GPU/hr from $0.17 | -- /GPU/hr from $0.04 | |
| Spot | -- /GPU/hr from $0.07 | -- /GPU/hr from $0.02 |
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 and spot on the Radeon RX 7900 XTX and on-demand and spot on the GTX 1660 Super: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning. More on how we price.
