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 |
|---|---|---|---|---|---|
| Accelerator | NVIDIA B200 SXM Accelerators CUDA (Blackwell) · TSMC 4NP · 1,000 W 100,000 NVIDIA Blackwell GPUs | NVIDIA | 100,000 reported | Verified | nvidianews.nvidia.comenergy.gov |

The read
The DOE, NVIDIA and Oracle announced in October 2025 a 100,000-GPU Blackwell system at Argonne, which both NVIDIA and the DOE independently state and which is the headline fact here. Both name the Blackwell family, not a specific part, so the accelerator edge maps to the B200 as the family's base part. The two systems are given a combined 2,200 exaflops of AI performance with no per-system figure, so no FLOPS are recorded. We found no later status update.

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.

- DOE, NVIDIA and Oracle announce Solstice and Equinox at Argonne · IT ProSolstice, with 100,000 Blackwell GPUs, and Equinox, with 10,000, are billed at a combined 2,200 exaflops of AI performance and sit at the same lab as Aurora, extending Argonne's fleet through a public-private financing model rather than the pure DOE-funded build Aurora was. Equinox is due in 2026; Solstice has no public delivery date yet, so neither belongs in the systems table until hardware lands.
