AMD MI355X
vs
Nvidia P4
Two data center GPUs, one CDNA 4 and one Pascal: 288 GB HBM3e against 8 GB GDDR5, 42x the memory bandwidth on the MI355X, and Infinity Fabric 1,075 GB/s on the MI355X where the P4 is PCIe only.

Price comparison
Median price per GPU per hour by billing type, with the cheapest listing under it.
| Billing | MI355X | P4 | Difference |
|---|---|---|---|
| On-demand | -- /GPU/hr from $8.60 | -- /GPU/hr from $0.65 | |
| Reserved | No reserved listings | -- /GPU/hr from $0.34 (36 mo) | |
| Spot | -- /GPU/hr from $4.50 | -- /GPU/hr from $0.12 |
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 on-demand, reserved and spot on the P4: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning.
