AMD MI300X
vs
Nvidia RTX 5090
A data center GPU against a consumer card, one CDNA 3 and one Blackwell: 192 GB HBM3 against 32 GB GDDR7, 3x the memory bandwidth on the MI300X, and Infinity Fabric 896 GB/s on the MI300X where the RTX 5090 is PCIe only.

| Spot | -- /GPU/hr from $1.60 | $0.35 /GPU/hr from $0.20 |
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 spot on the MI300X: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning. More on how we price.
