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 | - Dell Integrated Rack Scalable Systems and PowerEdge servers | Dell Technologies | - | Reported | nersc.govnersc.gov |
| Accelerator | NVIDIA Vera Rubin Accelerators NVIDIA Vera Rubin CPU-GPU platform | NVIDIA | - | Reported | nersc.gov |

The read
NERSC's next flagship, built by Dell on NVIDIA's Vera Rubin platform with Quantum-X800 InfiniBand, announced in May 2025 with full production due in late 2026. NERSC states only that it will deliver at least ten times Perlmutter's performance, which is not a FLOPS figure and is not recorded as one; no counts or power are published. Both pages are NERSC's own, so the tier is reported.

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 |
|---|---|---|
| nersc.gov | names system and part | NVIDIA Vera Rubin, NVIDIA InfiniBand XDR (Quantum-X800) |

- DOE names Dell and NVIDIA to build NERSC-10, Doudna · NVIDIA BlogDoudna succeeds Perlmutter at NERSC and is contracted for more than 10x Perlmutter's scientific output on 2 to 3x the power, an efficiency target that puts a specific number on the performance-per-watt gains this dataset already tracks across GPU generations. It ships on unreleased NVIDIA Vera Rubin parts, so nothing in the graph attaches to it yet beyond the contract.
