Price comparison

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

Billing	RTX 3080	RTX 4080	Difference
On-demand	$0.15 /GPU/hr from $0.11	$0.24 /GPU/hr from $0.16	39% cheaper on RTX 3080
Reserved	-- /GPU/hr from $0.12 (1 mo)	-- /GPU/hr from $0.34 (6 mo)
Spot	-- /GPU/hr from $0.06	-- /GPU/hr from $0.11

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 RTX 3080 and reserved and spot on the RTX 4080: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning.
