Phase 1 seed dataset — under review. These rows were compiled by hand from public operator, laboratory and vendor sources, and have not yet been through a second-reader verification pass. Every claim carries its source and a confidence tier; treat anything below verified as a lead, not a citation.

Measured performance

Rmax: 93.01 PFlop/s
Rpeak: 125.4 PFlop/s
Rmax ÷ Rpeak: 74.1%

Figures are as last publicly reported for the configuration described below, not a live measurement. Where a system was upgraded in place, the post-upgrade configuration is shown and the earlier one appears in the timeline.

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

The first No. 1 built on entirely domestically designed processors. No Intel, no AMD, no NVIDIA anywhere in the compute path: NRCPC's SW26010 manycore part, a domestic fabric, and a domestic OS. On our domestic-substitution index it is the first system in the dataset to score 1.0, six years before the question became a mainstream policy topic. Whether later Chinese systems sustained that score is the single most useful time series we publish.
