Price comparison
Median price per GPU per hour by billing type, with the cheapest listing under it.
| Billing | L4 | P40 | Difference |
|---|---|---|---|
| On-demand | $0.88 /GPU/hr from $0.32 | -- /GPU/hr from $0.11 | |
| Reserved | $0.52 /GPU/hr from $0.32 (36 mo) | No reserved listings | |
| Spot | $0.41 /GPU/hr from $0.13 | -- /GPU/hr from $0.07 |
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 P40: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning. More on how we price.
