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.

The read

ORNL's AI cluster, announced in October 2025 for deployment in 2026 on HPE ProLiant XD685 servers with AMD Instinct MI355X GPUs, EPYC CPUs and Pensando networking. We found no source showing it has gone live, so it stays planned. Counts, power and FLOPS are not published, and ORNL is the only source.

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.

None of the cited sources could be read from our network: the hosts returned bot challenges or did not respond. This check says nothing about the citations either way. See how this check works.

  • ORNL, AMD and HPE announce Discovery and Lux as Frontier's AI-era successors · Oak Ridge Leadership Computing Facility
    Lux runs AMD Instinct MI355X on HPE nodes with Oracle Cloud Infrastructure integration and arrives first, in 2026; Discovery follows in 2028 on MI430X and is billed as beating Frontier on every part of the system, not just peak flops. This keeps ORNL's AMD based lineage going a full hardware generation past the MI300A in El Capitan and the MI250X in Frontier.
