RTX 3090 vs RTX 4090: common questions

Is the RTX 3090 or the RTX 4090 cheaper to rent?

On Aquanode's live marketplace the RTX 3090 starts at $0.160/GPU/hr (median $0.224/GPU/hr across 3 providers) and the RTX 4090 starts at $0.336/GPU/hr (median $0.531/GPU/hr across 3 providers). The RTX 3090 is the cheaper of the two at the entry rate, by 52%.

What is the difference between the RTX 3090 and the RTX 4090?

Both cards report 24 GB of VRAM; the RTX 3090 is an Ampere part and the RTX 4090 is Ada Lovelace (compute capability 8.6 vs 8.9); only the RTX 4090 supports FP8 compute. On price, the RTX 3090 lists from $0.160/GPU/hr and the RTX 4090 from $0.336/GPU/hr.

Which cloud providers offer the RTX 3090 and the RTX 4090?

3 providers list the RTX 3090 (Simplepod, Akash and Vast.ai) and 3 list the RTX 4090 (Akash, Simplepod and Vast.ai), across 3 and 3 regions respectively. Both are available from Simplepod, Akash and Vast.ai.

How much does 1,000 GPU-hours cost on the RTX 3090 vs the RTX 4090?

At the lowest rates listed today, 1,000 GPU-hours costs $160 on the RTX 3090 and $336 on the RTX 4090 — a difference of $176 for the same runtime. Rates are per GPU per hour and update hourly.

How this comparison is calculated

Every price is normalized to a per-GPU hourly rate using the same pipeline as every other pricing surface on Aquanode, and only the cheapest qualifying offer per provider is shown. A dash means that provider does not currently list that GPU.

Architecture, compute capability and supported precisions come from each vendor's published datasheet for that generation — not from the marketplace feed. This page regenerates at most once per hour.
