H200 vs RTX 3070: Specs, VRAM & Price
Short answer: choose the H200 when 141 GB of VRAM is the gating requirement. Choose the RTX 3070 when 8 GB is enough for the workload and the lower hourly rate points that way.
The H200 has 141 GB of VRAM; the RTX 3070 has 8 GB.
You can rent both by the hour, no purchase required. H200 from $3.95/GPU/hr; RTX 3070 from $0.143/GPU/hr. The RTX 3070 is 96% cheaper at the entry rate.
H200

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 H200 page and RTX 3070 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.
