A data center GPU against a workstation card, one Blackwell Ultra and one Blackwell: up to 288 GB HBM3e against 48 GB GDDR7, 6x the memory bandwidth on the B300, and NVLink 1,800 GB/s on the B300 where the RTX PRO 5000 is PCIe only.

Price comparison
Median price per GPU per hour by billing type, with the cheapest listing under it.
| Billing | B300 | RTX PRO 5000 | Difference |
|---|---|---|---|
| On-demand | $7.89 /GPU/hr from $6.50 | Sold out | |
| Reserved | $5.71 /GPU/hr from $4.25 | -- /GPU/hr from $0.50 (24 mo) | |
| Spot | $5.85 /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 reserved on the RTX PRO 5000: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning. More on how we price.
