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.

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
AMD GPU system in Dell Technologies' HPC & AI Innovation Lab, listed by TOP500 as IronMan: PowerEdge XE9680 with Xeon Platinum 8460Y+ 40-core 2 GHz, AMD Instinct MI300X, Broadcom BCM957608 400G Ethernet and Ubuntu 22.04.5 LTS, installed 2024. It has 20,096 cores, Rmax 3.11 and Rpeak 5.27 PFlop/s (59 percent efficiency) with no power or HPCG figure, debuted at 339th in November 2024 and was 433rd in June 2026. It is a vendor showcase and benchmarking machine, in the line of the lab's Zenith (zenith-dell) and Rattler (rattler-dell), and its Ethernet fabric contrasts with the InfiniBand NDR of the lab's H100 machine Medusa (dell-medusa). TOP500 is the only source: no Dell page naming IronMan was found, so no site or in-service date is recorded and the tier is reported.
