A40 vs RTX 5080: common questions

Is the A40 or the RTX 5080 cheaper to rent?

On Aquanode's live marketplace the A40 starts at $0.075/GPU/hr (median $0.490/GPU/hr across 2 providers) and the RTX 5080 starts at $0.390/GPU/hr (median $0.390/GPU/hr across 2 providers). The A40 is the cheaper of the two at the entry rate, by 81%.

What is the difference between the A40 and the RTX 5080?

The A40 has 48 GB of VRAM against the RTX 5080's 16 GB; the A40 is an Ampere part and the RTX 5080 is Blackwell (compute capability 8.6 vs 12.0); only the RTX 5080 supports FP8 compute. On price, the A40 lists from $0.075/GPU/hr and the RTX 5080 from $0.390/GPU/hr.

Which cloud providers offer the A40 and the RTX 5080?

2 providers list the A40 (Vultr and RunPod) and 2 list the RTX 5080 (RunPod and Vast.ai), across 2 and 2 regions respectively. Both are available from RunPod.

How much does 1,000 GPU-hours cost on the A40 vs the RTX 5080?

At the lowest rates listed today, 1,000 GPU-hours costs $75 on the A40 and $390 on the RTX 5080, a difference of $315 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.
