Price comparison
Median price per GPU per hour by billing type, with the cheapest listing under it.
| Billing | L40S | RTX 4080 | Difference |
|---|---|---|---|
| On-demand | $1.29 /GPU/hr from $0.38 | $0.25 /GPU/hr from $0.23 | 5.2x more expensive on L40S |
| Reserved | $1.11 /GPU/hr from $0.60 (12 mo) | -- /GPU/hr from $0.20 (1 mo) | |
| Spot | $1.11 /GPU/hr from $0.74 | -- /GPU/hr from $0.11 |
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 reserved and spot on the RTX 4080: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning. More on how we price.
