A40 vs T4: common questions

Is the A40 or the T4 cheaper to rent?

On Aquanode's live marketplace the A40 starts at $0.075/GPU/hr (median $0.440/GPU/hr across 2 providers) and the T4 starts at $0.126/GPU/hr (median $0.126/GPU/hr across 1 provider). The A40 is the cheaper of the two at the entry rate, by 40%.

What is the difference between the A40 and the T4?

The A40 has 48 GB of VRAM against the T4's 16 GB; the A40 is an Ampere part and the T4 is Turing (compute capability 8.6 vs 7.5); only the A40 supports BF16 compute. On price, the A40 lists from $0.075/GPU/hr and the T4 from $0.126/GPU/hr.

Which cloud providers offer the A40 and the T4?

2 providers list the A40 (Vultr and RunPod) and 1 list the T4 (Akash), across 2 and 1 region respectively. No single provider currently lists both models.

How much does 1,000 GPU-hours cost on the A40 vs the T4?

At the lowest rates listed today, 1,000 GPU-hours costs $75 on the A40 and $126 on the T4 — a difference of $51 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.
