Price comparison

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

Billing	MI350X	RTX 5080
On-demand	No on-demand listings	$0.31 /GPU/hr from $0.22
Reserved	-- /GPU/hr from $4.76 (12 mo)	-- /GPU/hr from $0.27 (3 mo)
Spot	-- /GPU/hr from $2.46	-- /GPU/hr from $0.08

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 MI350X 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.
