Price comparison

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

Billing	A40	Quadro RTX 6000
On-demand	$0.65 /GPU/hr from $0.40	-- /GPU/hr from $0.13
Reserved	-- /GPU/hr from $0.61 (24 mo)	-- /GPU/hr from $0.12 (12 mo)
Spot	-- /GPU/hr from $0.27	No spot listings

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 A40 and on-demand and reserved on the Quadro RTX 6000: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning.
