GPU specialist against peer marketplace, priced against each other on the 7 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.
Spheron is cheaper on 4 of the 7 cards both of them rent, by a median of 22%. RunPod Secure Cloud is cheaper on the other 3.
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.

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 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. Spheron 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.
