Two Nvidia workstation GPUs, one Ampere and one Ada Lovelace: 48 GB GDDR6 against 20 GB GDDR6, 2.1x the memory bandwidth on the RTX A6000, and NVLink 112 GB/s on the RTX A6000 where the RTX 4000 Ada is PCIe only.

Price comparison
Median price per GPU per hour by billing type, with the cheapest listing under it.
| Billing | RTX A6000 | RTX 4000 Ada | Difference |
|---|---|---|---|
| On-demand | $0.56 /GPU/hr from $0.35 | $0.47 /GPU/hr from $0.19 | 16% cheaper on RTX 4000 Ada |
| Reserved | $0.54 /GPU/hr from $0.35 | -- /GPU/hr from $0.17 (3 mo) | |
| Spot | $0.43 /GPU/hr from $0.30 | -- /GPU/hr from $0.13 |
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 RTX 4000 Ada: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning. More on how we price.
