A data center GPU against a workstation card, one Ampere and one Turing: 40 GB HBM2 against 8 GB GDDR6, 3.7x the memory bandwidth on the A800, and NVLink 400 GB/s on the A800 where the RTX 4000 is PCIe only.

Price comparison
Median price per GPU per hour by billing type, with the cheapest listing under it.
| Billing | A800 | RTX 4000 | Difference |
|---|---|---|---|
| On-demand | -- /GPU/hr from $1.18 | -- /GPU/hr from $0.56 |
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 A800 and on-demand on the RTX 4000: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning. More on how we price.
