A data center GPU against a workstation card on the Ampere architecture: both with 48 GB GDDR6, 10% more memory bandwidth on the RTX A6000, and NVLink 112 GB/s on the RTX A6000 where the A40 is PCIe only.

Price comparison
Median price per GPU per hour by billing type, with the cheapest listing under it.
| Billing | A40 | RTX A6000 | Difference |
|---|---|---|---|
| On-demand | $1.05 /GPU/hr from $0.49 | $0.56 /GPU/hr from $0.35 | 46% cheaper on RTX A6000 |
| Reserved | -- /GPU/hr from $0.61 (24 mo) | $0.55 /GPU/hr from $0.35 | |
| Spot | -- /GPU/hr from $0.33 | $0.43 /GPU/hr from $0.30 |
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 A40: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning. More on how we price.
