Two Nvidia workstation GPUs, one Maxwell and one Turing: 2 GB DDR3 against 24 GB GDDR6, 23x the memory bandwidth on the Quadro RTX 6000, and NVLink 100 GB/s on the Quadro RTX 6000 where the K620 is PCIe only.

Price comparison
Median price per GPU per hour by billing type, with the cheapest listing under it.
| Billing | K620 | Quadro RTX 6000 | Difference |
|---|---|---|---|
| On-demand | No on-demand listings | -- /GPU/hr from $1.50 |
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 Quadro RTX 6000: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning. More on how we price.
