P4 vs V100: Specs, VRAM & Price
Short answer: choose the V100 when 16 GB of VRAM is the gating requirement. Choose the P4 when 8 GB is enough for the workload and the lower hourly rate points that way.
The P4 has 8 GB of VRAM; the V100 has 16 GB.
You can rent both by the hour, no purchase required. P4 from $0.069/GPU/hr; V100 from $0.088/GPU/hr. The P4 is 21% 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 P4 page and V100 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.
