AMD MI350X
vs
Nvidia L40
Two data center GPUs, one CDNA 4 and one Ada Lovelace: 288 GB HBM3e against 48 GB GDDR6, 9.3x the memory bandwidth on the MI350X, and Infinity Fabric 1,075 GB/s on the MI350X where the L40 is PCIe only.

Price comparison
Median price per GPU per hour by billing type, with the cheapest listing under it.
| Billing | MI350X | L40 | Difference |
|---|---|---|---|
| On-demand | No on-demand listings | $1.00 /GPU/hr from $0.45 | |
| Reserved | -- /GPU/hr from $4.76 (12 mo) | -- /GPU/hr from $0.70 | |
| Spot | -- /GPU/hr from $4.00 | $0.78 /GPU/hr from $0.27 |
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 on the L40: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning. More on how we price.
