Operated by evroc at evroc Arlandastad Site .
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: 1263 of 1345 systems have a readable citation that names them, and 56 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 Blackwell-based GPU cluster that evroc is bringing live; Arlandastad site capacity of up to 10,000 GPUs | NVIDIA | - | Reported | datacenter-forum.com |
| Cooling | - Liquid cooling for energy density above 150 kW per rack with excess heat recycled into district heating | evroc | - | Reported | datacenter-forum.com |

| Accelerators | 10,000 accelerators | 2025-07-08 | Design target | Arlandastad site has capacity for up to 10,000 GPUs; a planned site capacity, not an installed count. | datacenter-forum.com |

The read
evroc's flagship data center in Sweden, to be located at Arlandastad near Stockholm airport with capacity for up to 10,000 GPUs, liquid cooling and energy density above 150 kW per rack. It is designed to run on fossil-free energy and recycle excess heat into the local district heating network. Datacenter Forum reported on 8 July 2025, when evroc launched its sovereign cloud with an NVIDIA Blackwell-based GPU cluster, that Arlandastad was still the planned flagship; the 10,000 figure is a site capacity, not an installed count, and no MW figure is stated. A single trade-press source, so the tier is reported. It has never submitted an HPL result.
