Price comparison

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

Billing L40S RTX PRO 4000 Difference
On-demand $1.40 /GPU/hr from $0.55 -- /GPU/hr from $0.20
Reserved $1.10 /GPU/hr from $0.60 (12 mo) -- /GPU/hr from $0.26 (24 mo)
Spot $0.98 /GPU/hr from $0.40 -- /GPU/hr from $0.14

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, reserved and spot on the RTX PRO 4000: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning. More on how we price.
