MI325X vs P4

AMD MI325X vs Nvidia P4

Two data center GPUs, one CDNA 3 and one Pascal: 256 GB HBM3e against 8 GB GDDR5, 31x the memory bandwidth on the MI325X, and Infinity Fabric 896 GB/s on the MI325X where the P4 is PCIe only.

Price comparison

Median price per GPU per hour by billing type, with the cheapest listing under it.

Billing	MI325X	P4
On-demand	$3.07 /GPU/hr from $2.25	-- /GPU/hr from $0.65
Reserved	$1.95 /GPU/hr from $1.48 (12 mo)	-- /GPU/hr from $0.34 (36 mo)
Spot	Sold out	-- /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, 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. More on how we price.
