RTX 3090 vs RTX 4080 Super: common questions

Is the RTX 3090 or the RTX 4080 Super cheaper to rent?

On Aquanode's live marketplace the RTX 3090 starts at $0.160/GPU/hr (median $0.254/GPU/hr across 4 providers) and the RTX 4080 Super starts at $0.280/GPU/hr (median $0.390/GPU/hr across 2 providers). The RTX 3090 is the cheaper of the two at the entry rate, by 43%.

What is the difference between the RTX 3090 and the RTX 4080 Super?

The RTX 3090 has 24 GB of VRAM against the RTX 4080 Super's 16 GB; the RTX 3090 is an Ampere part and the RTX 4080 Super is Ada Lovelace (compute capability 8.6 vs 8.9); only the RTX 4080 Super supports FP8 compute. On price, the RTX 3090 lists from $0.160/GPU/hr and the RTX 4080 Super from $0.280/GPU/hr.

Which cloud providers offer the RTX 3090 and the RTX 4080 Super?

4 providers list the RTX 3090 (SimplePod, Akash, RunPod and Vast.ai) and 2 list the RTX 4080 Super (RunPod and Vast.ai), across 4 and 2 regions respectively. Both are available from RunPod and Vast.ai.

How much does 1,000 GPU-hours cost on the RTX 3090 vs the RTX 4080 Super?

At the lowest rates listed today, 1,000 GPU-hours costs $160 on the RTX 3090 and $280 on the RTX 4080 Super — a difference of $120 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.
