General-purpose cloud against peer marketplace, priced against each other on the 3 GPUs both of them rent. Published per-GPU on-demand rates as each provider last stated them, with what their own pages say about billing, commitment and egress beside the numbers.
Vast.ai is cheaper on 2 of the 3 cards both of them rent, by a median of 41%. Gcore is cheaper on the other 1.
These are not the same product. A general-purpose cloud and a peer marketplace differ in who your counterparty is, which is why the rates below can be far apart without either being wrong. The prices are comparable; what stands behind them is not.
The 3 cards both of them rent, cheapest published per-GPU on-demand rate each. Dearest first.
| GPU | Gcore | Vast.ai | Difference |
|---|---|---|---|
| NVIDIA H200 SXM5 141GB | ≈$3.11/hr | $4.08/hr | 24% cheaper on Gcore |
| NVIDIA H100 SXM5 80GB | ≈$2.58/hr | $1.87/hr | 28% cheaper on Vast.ai |
| NVIDIA A100 SXM4 80GB | ≈$1.45/hr | $0.67/hr | 54% cheaper on Vast.ai |
Per GPU per hour, on-demand list prices as each provider last published them. Rates exclude tax and vary by region; a cheaper rate is not the same machine, the same network or the same support.
| Gcore | Vast.ai | |
|---|---|---|
| Billing granularityOn short jobs this outweighs the rate: an hour minimum on a 90-second run costs more than a 30% dearer per-second rate. | Hourly (GPU); per minute (inference) | Per second |
| Minimum commitment | None on pay-as-you-go; subscription terms billed in full | $5 minimum to start |
| Payment model | Postpaid invoice by default; prepaid credits for some products; subscriptions | Prepaid credits; optional auto top-up |
| Free credits | Free trial periods offered; startup program | not stated |
| Egress | Free | Priced per byte by each host |
| Regions | 50+ cloud locations; 33 named on the cloud price list | 40+ data centres worldwide |
Neither site tells you whether your data trains their models, an uptime SLA, whether a commitment auto-renews or how long you have to dispute a bill. We looked on both and record the absence rather than filling it in — if you need any of it, ask before you commit.

Of the cards both rent, Gcore starts at $1.45 per GPU-hour and Vast.ai at $0.67.
No. Gcore is a general-purpose cloud — a hosting company where GPUs sit beside the VPS products, on the same account and billing. Vast.ai is a peer marketplace — a stranger whose machine the platform vets to some degree. Reliability, bandwidth and how long the machine stays online vary by host, not just by price. The rates are comparable; what stands behind them is not.
