L40 vs RTX 6000 Ada: Specs, VRAM & Price
Short answer: choose the L40 when you want the lower hourly rate and the specs are otherwise a wash. Choose the RTX 6000 Ada when RTX 6000 Ada pricing or availability works better where you're deploying.
Both the L40 and the RTX 6000 Ada ship with 48 GB of VRAM.
You can rent both by the hour, no purchase required. L40 from $0.759/GPU/hr; RTX 6000 Ada from $0.814/GPU/hr. The L40 is 7% 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 L40 page and RTX 6000 Ada 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.
