Price comparison

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

Billing	MI250	MI325X
On-demand	No on-demand listings	$3.07 /GPU/hr from $2.25
Reserved	-- /GPU/hr from $1.30 (12 mo)	$1.95 /GPU/hr from $1.48 (12 mo)
Spot	No spot listings	Sold out

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 on the MI250: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning. More on how we price.
