HOW TO CHOOSE
H800 vs H100 SXM
The H800 keeps about 76% of the H100's FP16 tensor throughput (1,513 vs 1,979 TFLOPS) but halves NVLink to 400 GB/s and drops FP64. Single-node training is close; scale-out training and HPC are not.
Workload fit
H100 SXM: llm pre-training, 70b+ fine-tuning, high-throughput inference. H800: llm training, large-batch inference, fp64 hpc.
H100 SXM VS H800 - FAQ

H100 SXM or H800 - which should I rent?
H100 SXM: The H100 SXM is the chip the current generation of frontier models was trained on, and the benchmark every other datacenter GPU is priced against. H800: The H800 was the first export-compliant Hopper for the China market: near-H100 tensor throughput but NVLink cut from 900 to 400 GB/s and FP64 essentially removed. The side-by-side spec table and live price rows above give the full picture.
