Google Columbus TPU Campus
Deep dive: Anthropic and Google TPUs: stated vs modelled
Also known as Google Columbus (Ohio)
Operated by Alphabet at Google Columbus 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
Google's Columbus, Ohio data center campus, one of three Central Ohio Google sites with New Albany and Lancaster. Google's Ohio page records more than 20 billion dollars invested in Ohio since 2019 and an operational Columbus Google Cloud region; it gives no TPU count or power for this campus. Epoch AI's AI data centers dataset (CC BY 4.0) estimates about 193,900 TPU v5e, 28,200 TPU v5p, 204,600 TPU v6e and 38,900 TPU v7 chips and 303 MW of IT power as of 2 October 2026, first building operational April 2024, from satellite imagery, cooling equipment and an AEP transmission construction notice. Those figures are modelled third-party estimates and sit in the metrics table only. Google reports a campus trailing-twelve-month PUE of 1.06 (Q2 2026). Hardware rests on Epoch alone, so the tier is 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.
| Cited source | Result | Found on the page |
|---|---|---|
| datacenters.google | names system and part | Google TPU v5p, Google TPU v6e (Trillium), Google TPU7x (Ironwood) |
| epoch.ai | names system and part | Google TPU v5p, Google TPU v6e (Trillium), Google TPU7x (Ironwood) |
