Price comparison
Median price per GPU per hour by billing type, with the cheapest listing under it.
| Billing | MI350P | MI355X | Difference |
|---|---|---|---|
| On-demand | No on-demand listings | $8.04 /GPU/hr from $5.99 | |
| Reserved | No reserved listings | -- /GPU/hr from $4.29 | |
| Spot | No spot listings | -- /GPU/hr from $3.44 |
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 MI355X: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning. More on how we price.
