A40 vs RTX 3060: Specs, VRAM & Price

Short answer: choose the A40 when 48 GB of VRAM is the gating requirement. Choose the RTX 3060 when 12 GB is enough for the workload and the lower hourly rate points that way.

The A40 has 48 GB of VRAM; the RTX 3060 has 12 GB.

You can rent both by the hour, no purchase required. A40 from $0.649/GPU/hr; RTX 3060 from $0.110/GPU/hr. The RTX 3060 is 83% cheaper at the entry rate.

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.

Memory bandwidth, tensor TFLOPS, NVLink/interconnect and max board power are the same verified-from-datasheet figures shown on each model's own A40 page and RTX 3060 page, which link the primary vendor source for that model. A dash here means Aquanode hasn't verified that figure from a primary source yet, never a guess.
