L40S vs Quadro M4000: Specs, VRAM & Price
Short answer: choose the L40S when 48 GB of VRAM is the gating requirement. Choose the Quadro M4000 when 8 GB is enough for the workload and the lower hourly rate points that way.
The L40S has 48 GB of VRAM; the Quadro M4000 has 8 GB.
You can rent both by the hour, no purchase required. L40S from $0.726/GPU/hr; Quadro M4000 from $0.069/GPU/hr. The Quadro M4000 is 90% cheaper at the entry rate.
L40S
Good for fine-tuning mid-size models and high-throughput inference
Quadro M4000

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 L40S page and Quadro M4000 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.
