NVIDIA L40S vs NVIDIA V100 32GB for local LLMs

2 reports on the NVIDIA L40S and 28 on the NVIDIA V100 32GB

Which is faster for local LLMs?

Nobody has reported the same model at the same quant on both cards yet, so there's no measured head-to-head. Memory bandwidth, which caps how fast a card can write, is about the same on both (864 GB/s on the NVIDIA L40S, 900 on the NVIDIA V100 32GB). The estimates below compare them on the models people run most.
