H100 80GB SXM for local AI
The standard datacenter GPU for LLM serving, with native FP8. Same memory as the A100 80GB but about 1.6 times the bandwidth. PCIe versions have lower bandwidth (2 TB/s).
Among the 2 devices we track with about 80 GB of usable memory, the H100 80GB SXM is the fastest at generating text, because generation speed follows memory bandwidth. Others in the same class: A100 80GB. They all hold the same models; the faster ones simply answer sooner.
Our picks for the H100 80GB SXM
The model we would run first for each job, chosen from our recommendations by what fits fully with an 8K context. "Best quant" is the highest quality that fits; "max context" is at Q4_K_M or the native format.
