Price comparison

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

Billing GTX 1660 Super P40 Difference
On-demand -- /GPU/hr from $0.04 -- /GPU/hr from $0.11
Spot -- /GPU/hr from $0.02 -- /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 on-demand and spot on the GTX 1660 Super and on-demand and spot on the P40: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning.
