Two Nvidia data center GPUs, one Ampere and one Volta: 48 GB GDDR6 against 32 GB HBM2, 29% more memory bandwidth on the V100, and NVLink 300 GB/s on the V100 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 | V100 | Difference |
|---|---|---|---|
| On-demand | $0.77 /GPU/hr from $0.49 | $0.95 /GPU/hr from $0.07 | 19% cheaper on A40 |
| Reserved | -- /GPU/hr from $0.61 (24 mo) | $0.97 /GPU/hr from $0.07 (3 mo) | |
| Spot | -- /GPU/hr from $0.40 | $0.43 /GPU/hr from $0.08 |
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.
