Price comparison

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

Billing	A4000	RTX A6000	Difference
On-demand	$0.21 /GPU/hr from $0.07	$0.56 /GPU/hr from $0.35	64% cheaper on A4000
Reserved	$0.18 /GPU/hr from $0.06 (6 mo)	$0.48 /GPU/hr from $0.26 (6 mo)	63% cheaper on A4000
Spot	-- /GPU/hr from $0.06	$0.33 /GPU/hr from $0.13

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 spot on the A4000: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning. More on how we price.
