L40S 48GB vs V100 16GB PCIe for Local LLMs

The V100 16GB PCIe has about 4% more memory bandwidth (900 vs 864 GB/s). Batch-1 decode tracks bandwidth closely, so a model that fits both cards should decode roughly 4% faster on the V100 16GB PCIe. The L40S 48GB fits more of the catalog at Q4/8K — 46 vs 25 of 73 models (48 vs 16 GB VRAM). Largest model that fits the L40S 48GB but not the V100 16GB PCIe: Qwen3-Next-80B-A3B-Instruct (81.3B). MSRP is $8,000 for the L40S 48GB vs $8,000 for the V100 16GB PCIe. MSRP is a launch list price, not live retail — Amazon prices move; click through for the current price. Not retail-shoppable: V100 16GB PCIe (datacenter-class; cloud rental is the realistic way to use it). In the Q4/8K head-to-head below (49 shared models), the V100 16GB PCIe posts the higher tok/s in 40 rows vs 9. Methodology.
