Data Center Infrastructure Grows 18% in Q2 2025
The Data Center Physical Infrastructure (DCPI) market experienced an 18% year-over-year growth in the second quarter of 2025, reaching $8.9 billion in manufacturer revenue, announced in a press release by Dell'Oro Group. This marks the third consecutive quarter of high growth, fueled by the ongoing expansion in AI technologies.
Direct liquid cooling technology has surged by 156% year-over-year, becoming the standard for large AI clusters. This shift is part of a broader trend where hyperscalers and colocation providers are rapidly scaling their capacities. The power distribution market also saw a 26% increase, driven by the adoption of overhead busways and intelligent rack PDUs.
North America led the regional growth with a 23% increase, while EMEA and Asia Pacific are expected to gain momentum. Hyperscalers and colocation providers accounted for over 80% of the expansion, highlighting their pivotal role in the AI-driven growth of data center infrastructure. Dell'Oro Group continues to provide comprehensive insights into these market dynamics.

Tensordyne Napier: What If One Rack Could Do the Work of Nine?
Tensordyne
This Tensordyne whitepaper presents Napier, an inference-focused AI processor and rack-scale system based on the company’s TDN Math logarithmic number system. It examines infrastructure requirements for large mixture-of-experts and agentic models, compares major inference architecture approaches, and details the TDN AIP processor, TDN72 pod, TDN Link fabric, and Napier Ultra configuration. The paper reports simulation-based performance, cost, and accuracy-validation results, including Tensordyne’s projected comparison of one Napier rack with a nine-rack Nvidia Rubin plus Groq deployment; the chip is reported as taped out and in fabrication.
