Price comparison
Cheapest listed price per GPU per hour by billing type, and the median across providers.
| Billing | A100 | RTX 4080 | Difference |
|---|---|---|---|
| On-demand | $0.89 | $0.17 | 5.1x more expensive on A100 |
| Spot | $0.68 | $0.11 | 6.2x more expensive on A100 |
| Reserved | $0.66 | No reserved listings | |
| Median | $1.79 | $0.25 | 7.2x more expensive on A100 |
Median: Median across providers, one vote each, so a large catalog does not outweigh a small one.
