A data center GPU against a workstation card, one Grace Blackwell and one Maxwell: 186 GB HBM3e against 2 GB DDR3, 276x the memory bandwidth on the GB200, and NVLink 1,800 GB/s on the GB200 where the K620 is PCIe only.

Price comparison
Median price per GPU per hour by billing type, with the cheapest listing under it.
| Billing | GB200 | K620 | Difference |
|---|---|---|---|
| On-demand | $16.00 /GPU/hr from $10.50 | No on-demand listings | |
| Reserved | -- /GPU/hr from $10.58 | No reserved listings | |
| Spot | -- /GPU/hr from $27.04 | 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 and spot on the GB200: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning. More on how we price.
