Phase 1 seed dataset, compiled by hand. These rows were built from public operator, laboratory and vendor sources. A mechanical second-reader pass has since fetched every cited source: 1092 of 1153 systems have a readable citation that names them, and 40 are genuinely weakly sourced. Every claim carries its source and a confidence tier. Treat anything below verified as a lead, not a citation.

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.
| Role | Part | Supplier at build | Quantity | Confidence | Source |
|---|---|---|---|---|---|
| Integrator | - NRCPC-built Sunway exascale-class system housed at the National Supercomputing Center in Wuxi | NRCPC | - | Reported | nextplatform.com |
| CPU | - Sunway SW26010-Pro, one per node, 107,520 nodes in the largest tested configuration (41.93 million cores) | NRCPC | 107,520 reported | Reported | nextplatform.com |
The read
NRCPC's exascale-class Sunway machine at the National Supercomputing Center in Wuxi, built on the SW26010-Pro CPU, with the largest tested configuration using 107,520 nodes and 41.93 million cores across 105 cabinets for about 1.51 exaflops peak (The Next Platform, March 2022, drawing on the 2021 Gordon Bell submissions). It was never submitted to the TOP500 and no Linpack figure is published in the page fetched, so ranked is 0 and only peak is recorded. A larger 160-cabinet configuration is speculation in the same article. Power is not published.

Source check
We fetched this system's own citations and recorded whether each page actually mentions it. This is a corroboration signal, not a fact check, and it is published so you can see how well the sourcing holds up rather than take it on trust.
