How to choose between L40S and A100 for GPU rental?

Straight answer: Select by task: For multi-GPU training, choose A100 80GB (NVLink interconnect + large VRAM); for single-GPU inference and graphics rendering, choose L40S 48GB. Pricing (as of 2026-11-12): L40S starts at ¥4.97/hour; A100 starts at ¥5.47/hour. L40S lacks NVLink—multi-GPU training communication becomes a bottleneck—but excels in FP8 inference efficiency, and its 48GB VRAM fits 32B-class quantized models perfectly.

GPU model	Architecture/Positioning	Current lowest monitored	Per day
L40S 48GB	Ada · Inference/Graphics	¥4.97/hour	¥119
A100 80GB	Ampere · Training	¥5.47/hour	¥131

One for training, one for inference

A100 is the classic training GPU: NVLink at 600 GB/s and 80 GB HBM2e — the de facto standard for data parallelism. L40S is an Ada-generation workstation GPU: strong FP8 inference throughput and RT Cores for rendering, but no NVLink and lower memory bandwidth (~864 GB/s). Using L40S for multi-GPU training or A100 for rendering is overspending.
