NVIDIA Data Center GPU H800 SXM5 80GB
The NVIDIA H800 SXM5 80GB is an enterprise AI accelerator based on the Hopper architecture, originally configured to comply with the initial 2022 US export control limits for China prior to the 2023 regulatory revisions. It maintains identical 80GB HBM3 memory capacity and 3.35 TB/s memory bandwidth to the standard H100 SXM5, but reduces the inter-GPU NVLink communication bandwidth to 400 GB/s (compared to 900 GB/s on the H100). This preserved full single-node training and inference performance while limiting massive multi-node scaling. Deployed in high-demand Chinese cloud data centers, second-hand buyers should verify board authenticity, test NVLink connectivity, and ensure proper 700W power delivery.

What was the difference between the H800 and the H100?
The H800 retained identical compute cores and 80GB HBM3 memory bandwidth, but capped NVLink interconnect bandwidth at 400 GB/s to comply with US export rules.
Is the H800 still produced?
No, following October 2023 US export control updates, the H800 was discontinued and succeeded by the H20.
What form factor does the H800 SXM5 use?
It uses the high-density SXM5 mezzanine module form factor for HGX 8-GPU baseboards.
