NVIDIA H100 80GB vs NVIDIA H100 NVL for local LLMs

6 reports on the NVIDIA H100 80GB and 0 on the NVIDIA H100 NVL

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 16% higher on the NVIDIA H100 NVL (3,350 GB/s on the NVIDIA H100 80GB, 3,900 on the NVIDIA H100 NVL). The estimates below compare them on the models people run most.
