L4 vs RTX PRO 6000 SE: Specs, VRAM & Price
Short answer: choose the RTX PRO 6000 SE when 96 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 L4 has 24 GB of VRAM; the RTX PRO 6000 SE has 96 GB.
You can rent both by the hour, no purchase required. L4 from $0.649/GPU/hr; RTX PRO 6000 SE from $2.15/GPU/hr. The L4 is 70% 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 L4 page and RTX PRO 6000 SE 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.
