A data center GPU against a workstation card, one Blackwell Ultra and one Pascal: up to 288 GB HBM3e against 16 GB GDDR5X, 28x the memory bandwidth on the B300, and NVLink 1,800 GB/s on the B300 where the P5000 is PCIe only.

Price comparison
Median price per GPU per hour by billing type, with the cheapest listing under it.
| Billing | B300 | P5000 | Difference |
|---|---|---|---|
| On-demand | $7.87 /GPU/hr from $6.50 | -- /GPU/hr from $0.78 | |
| Reserved | $5.71 /GPU/hr from $4.25 | No reserved listings | |
| Spot | $6.42 /GPU/hr from $4.30 | 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 on-demand on the P5000: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning. More on how we price.
