Price comparison

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

Billing	B300	RTX PRO 4500	Difference
On-demand	$8.50 /GPU/hr from $4.99	$0.82 /GPU/hr from $0.31	90% cheaper on RTX PRO 4500
Reserved	$6.25 /GPU/hr from $4.25	-- /GPU/hr from $0.33 (1 mo)
Spot	$5.55 /GPU/hr from $4.08	-- /GPU/hr from $0.18

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 PRO 4500: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning. More on how we price.
