Price comparison
Median price per GPU per hour by billing type, with the cheapest listing under it.
| Billing | MI325X | RTX 5080 | Difference |
|---|---|---|---|
| On-demand | $3.06 /GPU/hr from $2.25 | $0.30 /GPU/hr from $0.20 | 90% cheaper on RTX 5080 |
| Reserved | $1.95 /GPU/hr from $1.48 (12 mo) | -- /GPU/hr from $0.27 (1 mo) | |
| Spot | Sold out | -- /GPU/hr from $0.15 |
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 5080: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning. More on how we price.
