B200 vs L4: Specs, VRAM & Price
Short answer: choose the B200 when 180 GB of VRAM is the gating requirement. Choose the L4 when 24 GB is enough for the workload and the lower hourly rate points that way.
The B200 has 180 GB of VRAM; the L4 has 24 GB.
You can rent both by the hour, no purchase required. B200 from $7.47/GPU/hr across 3 providers; L4 from $0.478/GPU/hr across 2 providers. The L4 is 94% cheaper at the entry rate.
B200
Good for training and serving frontier-scale LLMs
L4
Good for inference and light fine-tuning workloads

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 B200 page and L4 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.
