What’s the difference between H20 and H100? Which one is more cost-effective to rent?

Q: What’s the difference between H20 and H100? Which one is more cost-effective to rent?

The H20 is a China-market variant of the H100, with a fundamentally different design: single-GPU compute is significantly lower than the H100, yet it features 96GB HBM3 and ~4TB/s memory bandwidth—higher than the H100’s ~3.35TB/s. Pricing (as of 2026-11-12): H20 starts at ¥3.40/hour; H100 starts at ¥8.28/hour. Conclusion: For large-model inference (bandwidth-sensitive), the H20 is often the best value option within mainland China; for training (compute-sensitive), the H20 is unsuitable—choose H100 or H800 instead.

Direct answer: The H20 is the China-market variant of the H100—but with a fundamentally different design focus: significantly lower per-GPU compute than the H100, yet higher memory capacity (96GB HBM3) and memory bandwidth (~4TB/s vs. H100’s ~3.35TB/s). Pricing (as of 2026-11-12): H20 starts at ¥3.40/hr; H100 starts at ¥8.28/hr. Conclusion: For large-model <b>inference</b> (memory-bandwidth-sensitive), the H20 is often the best value within mainland China; for <b>training</b> (compute-sensitive), the H20 is unsuitable—choose H100 or H800 instead.

Why ‘weaker’ GPUs are actually well-suited for inference

For LLM inference, the bottleneck is often memory bandwidth—not compute: each generated token requires loading all weights from VRAM; H20’s 4 TB/s bandwidth + 96 GB VRAM is a perfect match. Training, by contrast, relies heavily on matrix multiplication—compute is the bottleneck. This is a classic case of ’selecting architecture by workload’.
