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 | SambaNova RDU Accelerators Reconfigurable dataflow · TSMC 5nm air-cooled SambaNova SN40L systems; no rack count stated | SambaNova | - | Reported | intelligentcio.comuktech.news |

| Facility power | 600 MW | 2025-10 | Design target | Trade reports: first phase up to 600 MW (one says 100 to 600 MW), above 2 GW at full build-out. Upper bound of the first-phase range; campus-level planned figure. | intelligentcio.comuktech.news |
The read
Argyll Data Development and SambaNova's planned UK sovereign inference cloud at Killellan Farm on Scotland's Cowal Peninsula, a 184-acre campus using air-cooled SambaNova SN40L systems and a private-wire network of wind, wave and solar power with vanadium-flow battery storage. Trade coverage of the October 2025 announcement puts the first phase at up to 600 MW (one report says 100 to 600 MW) and the full build-out above 2 GW, with about GBP 15 billion of investment. SambaNova's own release names Argyll and the SN40L systems but gives no location or capacity, so the megawatt figures rest on the two trade pages. No rack or chip count is stated. 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.
