A data center GPU against a consumer card, one Blackwell and one Ampere: up to 192 GB HBM3e against 12 GB GDDR6X, 8.8x the memory bandwidth on the B100, and NVLink 1,800 GB/s on the B100 where the RTX 3080 Ti is PCIe only.

Price comparison
Median price per GPU per hour by billing type, with the cheapest listing under it.
| Billing | B100 | RTX 3080 Ti | Difference |
|---|---|---|---|
| On-demand | No on-demand listings | -- /GPU/hr from $0.15 | |
| Spot | No spot listings | -- /GPU/hr from $0.08 |
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 RTX 3080 Ti: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning. More on how we price.
