Price comparison

Median price per GPU per hour by billing type, with the cheapest listing under it.

Billing RTX 3090 RTX 4070 Difference
On-demand $0.21 /GPU/hr from $0.10 $0.16 /GPU/hr from $0.13 27% cheaper on RTX 4070
Reserved -- /GPU/hr from $0.06 (1 mo) No reserved listings
Spot -- /GPU/hr from $0.08 -- /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 reserved and spot on the RTX 3090 and spot on the RTX 4070: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning.
