Price comparison

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

Billing MI355X RTX 4070 Difference
On-demand -- /GPU/hr from $5.99 $0.15 /GPU/hr from $0.11

Spot -- /GPU/hr from $2.97 -- /GPU/hr from $0.06

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 on-demand and spot on the MI355X and reserved and spot on the RTX 4070: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning.
