Price comparison

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

Billing	P620	RTX 3090
On-demand	No on-demand listings	$0.20 /GPU/hr from $0.10
Reserved	No reserved listings	-- /GPU/hr from $0.06 (1 mo)
Spot	No spot listings	-- /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 RTX 3090: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning. More on how we price.
