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.

Measured performance

Rmax: 27.16 PFlop/s
Rpeak: 35.00 PFlop/s
Rmax ÷ Rpeak: 77.6%
Cores: 181,248
Power: 476.63 kW
Per watt: 57.0 GF/W

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 GPU (accelerated) partition of Pawsey's Setonix, an HPE Cray EX / AMD MI250X / Slingshot-11 national research system in Western Australia. Pawsey's own SC22 announcement states an efficiency of 56.983 GFlops/watt, which multiplied out against its own 476.63 kW power figure reproduces TOP500's 27.16 Pflops Rmax almost exactly, an independent mathematical confirmation of both figures, not merely a restatement of TOP500's own numbers.

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.

Cited source	Result	Found on the page
pawsey.org.au	names system and part	AMD EPYC 7A53 (Trento), AMD Instinct MI250X, HPE Cray Operating System
top500.org	names system and part	AMD EPYC 7A53 (Trento), AMD Instinct MI250X, HPE Slingshot-11, HPE Cray Operating System
