Microsoft Goodyear AI Datacenter
Also known as Microsoft Goodyear Arizona
Operated by Microsoft at Microsoft Goodyear Datacenter Campus .
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.
| Role | Part | Supplier at build | Quantity | Confidence | Source |
|---|---|---|---|---|---|
| Integrator | - Microsoft operates datacenters in Goodyear and El Mirage, Arizona (Greater Phoenix) | Microsoft | - | Reported | local.microsoft.com |
| Accelerator | - Epoch AI estimate: about 58,300 NVIDIA H100 GPUs (modelled) | NVIDIA | 58,300 estimated | Reported | epoch.ai |
| Accelerator | NVIDIA B200 SXM Accelerators CUDA (Blackwell) · TSMC 4NP · 1,000 W Epoch AI estimate: about 58,100 NVIDIA B200 GPUs (modelled) | NVIDIA | 58,100 estimated | Reported | epoch.ai |
AI datacenter metrics
Figures beyond an accelerator count, each with who stated it. What can and cannot be compared across AI datacenters.
| Metric | Value | As of | Basis | Note | Source |
|---|---|---|---|---|---|
| Accelerators | 116,400 accelerators | 2026-10-02 | Third-party estimate | About 58,300 H100 and 58,100 B200 (sum is ours); SemiAnalysis describes roughly 130,000 GPUs across four Arizona buildings. Epoch AI chip estimate (modelled from satellite imagery, cooling equipment and chip availability); not an operator disclosure. | epoch.ai |
| Stated investment | 7.7 USD bn | 2026-10-02 | Third-party estimate | Epoch AI modelled build cost, compute plus construction, 2025 USD, scaled from IT power; not a disclosed spend. | epoch.ai |
| IT power | 202 MW | 2026-10-02 | Third-party estimate | Epoch AI modelled IT power from satellite imagery and permits; not operator-stated. | epoch.ai |
The read
Microsoft's Goodyear, Arizona datacenter campus (the PHX10 to PHX12 buildings on W Broadway Road, part of the West US 3 Azure region), which Epoch AI tracks as a Microsoft AI-compute site. Microsoft's Greater Phoenix community page confirms it operates datacenters in Goodyear and El Mirage but gives no hardware, MW or AI detail for the site. SemiAnalysis, summarised from its public article, describes an Arizona cluster of roughly 130,000 GPUs across four buildings, with H100 in 2023, H200 in 2024 and GB200 in 2025. Epoch AI's AI data centers dataset (CC BY 4.0) estimates about 58,300 H100 and 58,100 B200 chips and 202 MW of IT power as of 2 October 2026, with the first AI building operational in April 2023 (Epoch's date for AI compute, not the 2021 region launch), derived from Maricopa County permit records and satellite imagery. The estimates sit in the metrics table only. Hardware rests on third-party analysts, 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 |
|---|---|---|
| epoch.ai | names system and part | NVIDIA B200 SXM |
