A workstation GPU against a data center card, one Ampere and one Blackwell: 16 GB GDDR6 against up to 192 GB HBM3e, 18x the memory bandwidth on the B100, and NVLink 1,800 GB/s on the B100 where the A4000 is PCIe only.

Price comparison
Median price per GPU per hour by billing type, with the cheapest listing under it.
| Billing | A4000 | B100 | Difference |
|---|---|---|---|
| On-demand | $0.21 /GPU/hr from $0.15 | No on-demand listings | |
| Reserved | $0.25 /GPU/hr from $0.11 | No reserved listings | |
| Spot | -- /GPU/hr from $0.10 | No spot listings |
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 A4000: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning. More on how we price.
