Massive AI Data Center Buildout Faces Power Constraints
According to reports from industry executives, the massive AI data center buildout occurring among the world’s largest tech companies faces significant power constraints that could limit growth. Mohamed Awad, senior vice president and general manager of Arm’s infrastructure business, stated there is “no doubt about the long-run need” for this expansion despite current challenges.
“If you think about it from a long-range perspective, there’s no doubt that all this is going to be required because we’re just in its infancy, and we’re still learning and developing,” Awad said in an interview, as reported by CRN. Sources indicate that the industry is shifting from training-focused growth to inference-driven demand as agentic AI applications become more capable.
Recent Mega-Deals Highlight Scale of AI Infrastructure Push
The report states that recent weeks have seen several gargantuan AI data center agreements, including OpenAI’s infrastructure deals involving both Nvidia and AMD GPU platforms. This week alone witnessed multiple major announcements, including OpenAI’s collaboration with Broadcom for custom AI accelerator chips and Oracle’s 50,000-GPU agreement with AMD.
Analysts suggest these deals reflect the growing scale needed for advanced AI models. “The scale of what’s being needed right now, especially when you’re talking about these agentic models, these larger reasoning models, they’re large,” said Andy Lin, CTO of systems integrator Mark III Systems, according to the report.
Power Availability Emerges as Critical Bottleneck
Industry executives reportedly acknowledge that power constraints represent a major obstacle to the planned AI data center expansion. Awad emphasized that while funding is available, power availability remains the limiting factor.
“In some ways, money is free, and obviously I don’t mean it’s free, but people can get money. It’s not about money. It’s about how much power can I get, and can I meet that demand? And the reality is, you just can’t build the data centers fast enough,” he stated, according to the report.
Arm Introduces New Chiplet Standard to Address Energy Challenges
To help address these energy consumption issues, Arm announced it is contributing the Foundation Chiplet System Architecture specification to the Open Compute Project. The move reportedly aims to provide tech companies with a new standard for building custom, chiplet-based silicon products that can maximize performance per watt.
Sources indicate that the specification builds on Arm’s Chiplet System Architecture introduced last year, which standardizes how chiplets are partitioned and communicate with each other on chiplet-based silicon packages using Arm CPU cores. “What we’ve decided is that the wider industry can benefit from this. This shouldn’t be just tied to Arm,” Awad stated.
Open Standard Supports Multiple Architectures
According to the report, by contributing the specification to OCP, companies will be able to build chiplet-based products using any instruction set architecture, including x86 used by AMD and Intel. This approach reportedly gives companies greater design freedom while maintaining performance within set power envelopes.
“In that environment where performance per watt matters a lot what we’re seeing more and more is that big technology providers who are building data centers are specifying all aspects of the system to eke out as much performance as possible,” Awad explained.
Arm’s Position in the Evolving AI Infrastructure Market
Despite the specification being open to any architecture, analysts suggest Arm expects to benefit through its competitive compute offerings like Neoverse CPU core designs. The company reportedly offers a middle ground between fully custom silicon development and off-the-shelf products.
According to the report, Arm has established its Arm Total Design ecosystem program to connect companies with compute needs to chip designers, manufacturers, and technology providers. This comes as major tech companies continue expanding their AI capabilities and as regulatory environments evolve alongside workplace transformations driven by AI adoption.
Awad expressed confidence in Arm’s long-term prospects, citing the company’s existing footprint of more than 300 billion devices and the breadth of its offerings. “This is a very big market, and there is a lot happening. And I think the breadth of our offering and the breadth of our footprint bodes well,” he stated, according to the report.
