GPU specialist against peer marketplace, priced against each other on the 13 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.

These are not the same product. A GPU specialist 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 13 cards both of them rent, cheapest published per-GPU on-demand rate each. Dearest first.

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.

Neither site tells you whether your data trains their models, whether you get credits when it breaks, how long you have to dispute a bill or how much warning you get before maintenance. We looked on both and record the absence rather than filling it in — if you need any of it, ask before you commit.

No. RunPod Secure Cloud is a GPU specialist — an operator whose whole business is renting these cards. 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.
