HOW TO CHOOSE
H100 PCIe vs H100 SXM
SXM has ~30% more compute, 67% more memory bandwidth and real NVLink fabric - and usually a matching price premium. Single-card and inference work sees little of that gap.
Workload fit
H100 PCIe: inference, fine-tuning. H100 SXM: llm pre-training, 70b+ fine-tuning, high-throughput inference.
