What’s the difference between H800 and H100? Which one is more cost-effective to rent?

Direct answer: The H800 is the China-market variant of the H100: near-identical per-GPU compute specs, with the primary difference being inter-GPU interconnect (NVLink) bandwidth—public data shows reduction from ~900GB/s on the H100 to ~600GB/s on the H800, meaning slower multi-GPU communication but negligible impact on single-GPU inference. Pricing (as of 2026-11-12): H100 80GB starts at ¥8.28/hr; H800 80GB starts at ¥10.50/hr. For single-GPU inference or fine-tuning, choose the cheaper option. For large-model multi-GPU parallel training—which is highly sensitive to interconnect bandwidth—prioritize H100 clusters.
| GPU model | Use case positioning | Current lowest monitored | Platform |
|---|
| H100 80GB | Overseas edition flagship | ¥8.28/hour | Paperspace (United States) |
| H800 80GB | China-market special edition | ¥10.50/hour | AutoDL |
What Are Special Editions?
Since 2022, U.S. export controls have restricted sales of high-end AI chips to China. NVIDIA subsequently launched China-market-specific models—including the H800, A800, and H20—with full per-GPU compute retained but reduced inter-GPU or memory bandwidth to comply with regulatory definitions. Our site tracks day-by-day both their relationship to original models and platform pricing across vendors.
Selection criteria
① Single-GPU or small-scale inference/fine-tuning: bandwidth differences have minimal impact — direct price comparison suffices; ② Multi-GPU data-parallel training: AllReduce communication volume strongly depends on interconnect bandwidth — H100 clusters hold clear advantages; ③ When budget is primary: H800 offers more stable supply and lower pricing year-round, making it the mainstream choice for domestic training.
Methodology
Interconnect bandwidth figures are sourced from NVIDIA’s public documentation and mainstream media reports, for order-of-magnitude reference only; prices are live public quotes scraped by this site every 45 minutes — always verify against the platform’s official checkout page.
