Two Nvidia data center GPUs, one Ampere and one Pascal: 80 GB HBM2e against 8 GB GDDR5, 10x the memory bandwidth on the A100, and NVLink 600 GB/s on the A100 where the P4 is PCIe only.

Price comparison
Median price per GPU per hour by billing type, with the cheapest listing under it.
| Billing | A100 | P4 | Difference |
|---|---|---|---|
| On-demand | $1.77 /GPU/hr from $0.80 | -- /GPU/hr from $0.65 | |
| Reserved | $1.66 /GPU/hr from $0.65 (3 mo) | -- /GPU/hr from $0.34 (36 mo) | |
| Spot | $1.20 /GPU/hr from $0.68 | -- /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.
