Price comparison

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

Billing	A40	RTX 5080	Difference
On-demand	$0.85 /GPU/hr from $0.59	$0.34 /GPU/hr from $0.26	59% cheaper on RTX 5080
Reserved	-- /GPU/hr from $0.61 (24 mo)	No reserved listings
Spot	No spot listings	-- /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 on the A40 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. More on how we price.
