Frequently Asked Questions

Why choose the H800?

80GB HBM3 with FP8 Transformer Engine, similar compute to H100. Available in the Chinese market where H100 is restricted. 400 GB/s NVLink still supports multi-GPU training.

When is the H800 not a good fit?

Reduced NVLink bandwidth (400 vs 900 GB/s) compared to H100. Not ideal for communication-heavy distributed training across many nodes. Outside China, the H100 is typically a better choice.
