Price comparison
Median price per GPU per hour by billing type, with the cheapest listing under it.
| Billing | L40S | T4G | Difference |
|---|---|---|---|
| On-demand | $1.57 /GPU/hr from $0.55 | -- /GPU/hr from $0.42 | |
| Reserved | $1.10 /GPU/hr from $0.61 (12 mo) | -- /GPU/hr from $0.18 (36 mo) | |
| Spot | $0.99 /GPU/hr from $0.74 | 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 on-demand and reserved on the T4G: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning. More on how we price.
