L4 vs RTX A5000: Specs, VRAM & Price
Short answer: choose the L4 when your workload uses FP8 quantized inference or serving. Choose the RTX A5000 when your workload is BF16/FP32-only and FP8 buys you nothing.
Both the L4 and the RTX A5000 ship with 24 GB of VRAM.
You can rent both by the hour, no purchase required. L4 from $0.478/GPU/hr across 2 providers; RTX A5000 from $0.176/GPU/hr across 2 providers. The RTX A5000 is 63% cheaper at the entry rate.
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 L4 page and RTX A5000 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.
