Two Nvidia data center GPUs, one Hopper and one Kepler: 80 GB HBM3 against 12 GB GDDR5, 14x the memory bandwidth on the H100, and NVLink 900 GB/s on the H100 where the K80 is PCIe only.

Price comparison
Median price per GPU per hour by billing type, with the cheapest listing under it.
| Billing | H100 | K80 | Difference |
|---|---|---|---|
| On-demand | $3.39 /GPU/hr from $1.50 | -- /GPU/hr from $0.90 | |
| Reserved | $3.16 /GPU/hr from $1.53 (1 mo) | -- /GPU/hr from $0.04 (24 mo) | |
| Spot | $2.15 /GPU/hr from $0.14 | 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 on-demand and reserved on the K80: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning. More on how we price.
