Price comparison

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

Billing	Radeon RX 7900 XTX	RTX 5080	Difference
On-demand	-- /GPU/hr from $0.17	$0.34 /GPU/hr from $0.23
Spot	-- /GPU/hr from $0.07	-- /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 on-demand and spot on the Radeon RX 7900 XTX 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.
