A consumer GPU against a workstation card, one Ampere and one Turing: 24 GB GDDR6X against 8 GB GDDR6, 2.2x the memory bandwidth on the RTX 3090, and NVLink 112 GB/s on the RTX 3090 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 | RTX 3090 | RTX 4000 | Difference |
|---|---|---|---|
| On-demand | $0.20 /GPU/hr from $0.10 | -- /GPU/hr from $0.56 | |
| Reserved | -- /GPU/hr from $0.06 (1 mo) | No reserved listings | |
| Spot | $0.11 /GPU/hr from $0.07 | 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 on the RTX 3090 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.
