AMD MI350X
vs
Nvidia RTX 3080
A data center GPU against a consumer card, one CDNA 4 and one Ampere: 288 GB HBM3e against 10 GB GDDR6X, 11x the memory bandwidth on the MI350X, and Infinity Fabric 1,075 GB/s on the MI350X where the RTX 3080 is PCIe only.

Price comparison
Median price per GPU per hour by billing type, with the cheapest listing under it.
| Billing | MI350X | RTX 3080 | Difference |
|---|---|---|---|
| On-demand | No on-demand listings | $0.15 /GPU/hr from $0.08 | |
| Reserved | -- /GPU/hr from $4.76 (12 mo) | -- /GPU/hr from $0.19 (3 mo) | |
| Spot | -- /GPU/hr from $4.00 | -- /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 reserved and spot on the MI350X and reserved and spot on the RTX 3080: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning.
