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

Billing A40 RTX 5080 Difference
On-demand $0.65 /GPU/hr from $0.40 $0.28 /GPU/hr from $0.22 57% cheaper on RTX 5080

Spot -- /GPU/hr from $0.27 -- /GPU/hr from $0.15

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 A40 and reserved and spot on the RTX 5080: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning.
