TensorWave Tucson MI325X Cluster
Operated by TensorWave at TensorWave Tucson Data Center .
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
TensorWave's 8,192-GPU AMD Instinct MI325X training cluster, described by the company as the largest AMD training deployment in North America and the neocloud row in this dataset that is built entirely on AMD accelerators. Tom's Hardware (July 2025) and Futuriom (August 2025) independently give the 8,192 MI325X count and describe the cluster as deployed and running, with Tom's Hardware also describing a direct-to-chip liquid cooling loop; SiliconANGLE's May 2025 funding report places it at a data center campus in Tucson, Arizona, where the cluster was then targeted for completion by the end of June 2025 with about 1,000 GPUs installed. Aggregate compute is stated by the trade press as roughly 21 exaflops of FP8, a vendor peak figure that is not recorded as FLOPS here. No source states the server vendor, network fabric or a site power figure for this specific cluster. TensorWave later announced a further 20 MW split between Tucson and Pennsylvania with TECfusions. It has never submitted an HPL result.

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.
