RTX 3060 vs RTX 4080 Super: Specs, VRAM & Price
Short answer: choose the RTX 4080 Super when 32 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 RTX 3060 has 12 GB of VRAM; the RTX 4080 Super has 32 GB.
You can rent both by the hour, no purchase required. RTX 3060 from $0.110/GPU/hr across 2 providers; RTX 4080 Super from $0.338/GPU/hr across 1 provider. The RTX 3060 is 68% 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 RTX 3060 page and RTX 4080 Super 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.
