Researched with AI assistance, checked by scripts. These rows were researched by AI agents reading public operator, laboratory and vendor sources, appended by scripts and checked by automated validation; no subject-matter expert has reviewed them (how this site is made). A mechanical second-reader pass has since fetched every cited source: 1350 of 1540 systems have a readable citation that names them, and 64 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 | - Elea Data Centers develops RJO2 (80 MW, 2026), RJO3 and RJO4 (about 120 MW) toward a 1.5 GW first phase | Elea Data Centers | - | Reported | teletime.com.brbaguete.com.br |
AI datacenter metrics
Figures beyond an accelerator count, each with who stated it. What can and cannot be compared across AI datacenters.
| Metric | Value | As of | Basis | Note | Source |
|---|---|---|---|---|---|
| Facility power | 1,500 MW | 2025-05 | Design target | First-phase target; RJO2 adds about 80 MW in 2026 and RJO3 plus RJO4 about 120 MW | teletime.com.brbaguete.com.br |
The read
Elea Data Centers' plan for a district of AI and cloud data centers in the Olympic Park area of Barra da Tijuca, Rio de Janeiro, backed by the city government. Teletime and Baguete (8 to 9 May 2025) report an existing RJO1 data center, a second Rio data center adding 80 MW in 2026, RJO3 and RJO4 adding roughly 120 MW together, then expansion to a first phase of 1.5 GW and a potential 3.2 GW; the IoT M2M Council write-up (11 May 2025) names the 80 MW unit RJO2 as under construction, which the two press pieces do not. Power is stated to be entirely renewable and cooling waterless. Reported investment is only 'billions of dollars' with no figure, and no GPU count or tenant is stated.

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.
One cited source was readable and does not mention this system; another could not be read because the host returned a bot challenge. The unreadable one may well be fine, so this is weaker evidence than a corroborated row and much stronger than an unsupported one. See how this check works.
