A data center GPU against a consumer card, one Pascal and one Ampere: 16 GB HBM2 against 10 GB GDDR6X, memory bandwidth within 5%, and NVLink 160 GB/s on the P100 where the RTX 3080 is PCIe only.

Price comparison
Median price per GPU per hour by billing type, with the cheapest listing under it.
| Billing | P100 | RTX 3080 | Difference |
|---|---|---|---|
| On-demand | $1.53 /GPU/hr from $1.27 | -- /GPU/hr from $0.18 | |
| Reserved | $1.04 /GPU/hr from $0.12 (24 mo) | No reserved listings | |
| Spot | -- /GPU/hr from $0.77 | -- /GPU/hr from $0.06 |
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 P100 and on-demand and spot on the RTX 3080: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning. More on how we price.
