Two Nvidia data center GPUs, one Kepler and one Volta: 12 GB GDDR5 against 32 GB HBM2, 4.7x the memory bandwidth on the V100S, and NVLink 300 GB/s on the V100S where the K80 is PCIe only.

Price comparison
Median price per GPU per hour by billing type, with the cheapest listing under it.
| Billing | K80 | V100S | Difference |
|---|---|---|---|
| On-demand | -- /GPU/hr from $0.90 | -- /GPU/hr from $0.88 | |
| Reserved | -- /GPU/hr from $0.04 (24 mo) | No reserved 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 on-demand and reserved on the K80 and on-demand on the V100S: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning.
