AI super-densification: how far will it really go?
The data center industry is on the cusp of the hyperscale AI supercomputing era, where systems will be more powerful and denser than the cutting-edge exascale systems of today. But will this transformation really materialize?
Electrical considerations with large AI compute
Training large transformer models is different from all other workloads — data center operators need to reconsider their approach to both capacity planning and safety margins across their infrastructure.
Gen AI power consumption surges higher faster
The past year warrants a revision of generative AI power estimates, as GPU shipments have skyrocketed, despite some offsetting factors. However, uncertainty remains high, with no clarity on the viability of these spending levels.
Uncertainty and doubt as US changes GPU export rules again
The US government’s AI compute diffusion rules, introduced in January 2025, will be rescinded — with new rules coming. It warns any dealings linked to advanced Chinese chips will require US export authorization. Operators still face tough demands.
The booming data center sector grapples with tariff chaos
Seb
Shehadi
The global tariff crisis initiated by the US administration is expected to have strong, long-lasting effects on the data center sector, driving up prices and slowing growth.

Density choices for AI training are increasingly complex
High-end AI systems receive the bulk of the industry’s attention, but organizations looking for the best training infrastructure implementation have choices. Getting it right, however, may take a concerted effort.
Small modular reactors: building critical mass
SMRs promise to usher in an era of dispatchable low-carbon energy. At present, however, their future is a blurry expanse of possibilities rather than a clear path ahead, as key questions of costs, timelines and operations remain.
The DeepSeek paradox: more efficiency, more infrastructure?
The emergence of the Chinese DeepSeek LLM has raised many questions. In this analysis, Uptime Intelligence considers some of the implications for all those primarily concerned with the deployment of AI infrastructure.
AI infrastructure ambitions will be cut down to size
John
O'Brien
Operators and investors are planning to spend hundreds of billions of dollars on supersized sites and vast supporting infrastructures. However, increasing constraints and uncertainties will limit the scale of these build outs.
AI supremacy: how will the new US GPU export controls work?
The US government is applying a new set of rules to control the building of large AI clusters around the world. The application of these rules will be complex.
REPLAY | Five data center predictions for 2025
Uptime Intelligence surveys the data center industry landscape to look deeper at what can actually happen in 2025 and beyond based on the latest trends and developments. The stronghold that AI has on the industry is a constant discussion - but how…
