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
Google Cloud's public-preview cluster of Cloud TPU v4 Pods in its Mayes County, Oklahoma datacenter, announced on 11 May 2022 as 9 exaflops of peak aggregate performance at 90 percent carbon-free energy on an hourly basis, with a datacenter PUE of 1.10. Each pod is 4,096 chips; Google's blog gives no pod count and The Next Platform, quoting Google's CEO at I/O, reports eight pods, which is consistent with 9 exaflops at about 1.1 exaflops per pod, so the 32,768-chip total is derived and marked estimated. The 9 exaflops is a bfloat16 vendor peak on a different basis from HPL, so no FLOPS are recorded. It is a separate installation from the single 4,096-chip machine in the existing Google TPU v4 supercomputer row, whose site Google does not disclose. Both sources are Google's own statement, so this stays reported.

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.
