Viettel H200 AI Platform
Operated by Viettel Group .
Researched with AI assistance, checked by scripts. These rows were researched by AI agents reading public operator, laboratory and vendor sources, appended by scripts and checked by automated validation; no subject-matter expert has reviewed them (how this site is made). A mechanical second-reader pass has since fetched every cited source: 1350 of 1581 systems have a readable citation that names them, and 64 are genuinely weakly sourced. Every claim carries its source and a confidence tier. Treat anything below verified as a lead, not a citation.

How it compares
Ranked against the other machines in this dataset that report the same figure: those that first came into service within two years of Viettel H200 AI Platform, and those in Vietnam. Computed from our tables; a metric is ranked only when at least eight peers report it.
| Metric | Value | Against its era | Against its country |
|---|---|---|---|
| Rmax | 40.21 PFlop/s | #45 of 158 · top 28% | - |
| Rmax ÷ Rpeak | 71.4 % | #85 of 155 · bottom 46% | - |
Every metric is ranked largest-first, so a high power-draw rank means a big power draw, not a good one. Rmax ÷ Rpeak uses HPL-measured results only. Rankings move as machines are added; they describe this dataset, not the world.
What this machine is made of
One row per supplier relationship. “Supplier at build” is the company that shipped the part at the time; where that company has since been acquired, the parent it rolls up to today is shown beside it. That distinction is what makes ticker-level aggregation possible across a thirty-year dataset.

The read
ASUS HGX H200 cluster listed as Viettel AI Platform at rank 60 on the June 2026 TOP500, installed 2026: 123,264 cores of Xeon Platinum 8558 48-core hosts, NVIDIA H200 GPUs, NDR400 InfiniBand and Ubuntu 24.04.1, 40.21 PFlop/s Rmax and 56.28 PFlop/s Rpeak. TOP500 gives the system URL as viettelcloud.vn but no GPU count, site or power; the viettelcloud.vn page did not render any content when fetched, so there is no operator confirmation and the confidence stays reported. Viettel's separate DGX B200 machine at Hoa Lac is the row viettel-dgx-b200; this H200 system is a different TOP500 entry and the sources do not say whether they share a building. Ranked 0 here because the June 2026 list edition is already full in the dataset.
