Price comparison
Median price per GPU per hour by billing type, with the cheapest listing under it.
| Billing | RTX 4090 | RTX 6000 Ada | Difference |
|---|---|---|---|
| On-demand | $0.48 /GPU/hr from $0.30 | $1.07 /GPU/hr from $0.58 | 55% cheaper on RTX 4090 |
| Reserved | $0.52 /GPU/hr from $0.28 (3 mo) | $1.13 /GPU/hr from $0.55 (6 mo) | 54% cheaper on RTX 4090 |
| Spot | $0.32 /GPU/hr from $0.16 | -- /GPU/hr from $0.40 |
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 RTX 6000 Ada: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning. More on how we price.
