Over the past few years, the logic behind the development of the artificial intelligence industry has been crystal clear: whoever possesses greater computing power is more likely to gain a market advantage. As a result, GPUs have become the most sought-after core asset in the AI era, fueling a sustained investment boom around AI chips.
However, as large language models continue to scale up, the AI industry is entering a new phase.
Training a large AI model requires tens of thousands of GPUs working in tandem, and these GPUs don’t operate independently. They need high-speed network connectivity, substantial power support, a stable data center environment, and advanced storage and cooling systems to ensure long-term operation.
This shift means the bottleneck for AI development is moving from "do we have enough computing power" to "can we support such massive scale."
In the future, competition among AI data centers may not just be a battle between chips, but a contest among entire infrastructure systems.
AI Data Centers Enter the Era of Infrastructure Competition
AI data centers are fundamentally different from traditional data centers. Conventional cloud computing centers primarily serve web pages, databases, and enterprise software, with relatively stable computing demands. AI data centers, on the other hand, must support large-scale parallel computing, imposing much higher requirements for energy, networking, and hardware.
Especially with the rapid growth of generative AI, enterprises are increasingly demanding GPU clusters. A single AI data center may deploy tens of thousands—or even more—AI accelerators, and running these devices simultaneously creates enormous energy consumption and data exchange needs.
Previously, the market focused on:
- Who can manufacture more GPUs?
- Now, the market is shifting focus to:
- Who can build more AI data centers?
- Who can provide enough power?
- Who can ensure tens of thousands of GPUs work efficiently together?
This is why the AI industry chain is expanding beyond chip companies into broader infrastructure sectors.
Why Power Has Become the New Bottleneck for AI Expansion
One of the biggest changes in AI data centers is the dramatic increase in energy demand. While traditional data centers also consume significant power, AI workloads typically require much denser computing resources. Running large numbers of GPUs for extended periods drives power requirements even higher.
As global tech companies continue to ramp up investments in AI infrastructure, power supply is emerging as a new limiting factor. A large AI data center needs not only server equipment, but also a stable and reliable power system, including:
- Grid connectivity
- Power generation resources
- Power management systems
- Data center energy optimization technologies
This means that in the AI era, winners may include not just chip manufacturers, but also energy infrastructure companies. Historically, the tech industry and the energy sector operated independently, but AI is changing that relationship. Building an AI data center now involves not just buying GPUs, but also solving the challenge of "where to source enough power." This is why the market has increasingly focused on data center power supply, grid upgrades, and new energy infrastructure in recent years.
Network Interconnects Are Key to AI Cluster Efficiency
Beyond power, networking is another critical bottleneck for AI data centers. Training large AI models requires massive numbers of GPUs working together. If the data transfer speed between GPUs is insufficient, even abundant computing resources can’t reach their full potential.
Therefore, AI data centers need faster, lower-latency network architectures. High-speed switching chips, optical interconnect technologies, and advanced data center network equipment are becoming increasingly important. In traditional server environments, networks primarily handle data exchange. But in AI clusters, the network is a crucial factor affecting computing efficiency. Compute power determines performance; HBM dictates data supply speed; the network governs how computing resources collaborate.
This explains why the market has started paying more attention to AI network chip companies. Compared to simply manufacturing compute chips, network infrastructure providers may become another group of beneficiaries as AI expands.
Data Center Infrastructure Enters a New Growth Cycle
The evolution of AI data centers is driving upgrades across the entire infrastructure industry.
Server infrastructure. AI servers differ from traditional servers, requiring support for higher-performance GPUs, more complex cooling systems, and stronger power management capabilities.
Cooling technology. As chip performance improves, traditional air cooling is under pressure, and advanced solutions like liquid cooling are gaining traction.
Data center construction. AI data centers demand larger spaces, more stable energy supplies, and more robust network environments.
As a result, the AI industry chain is forming a new infrastructure ecosystem:
Upstream: AI chips, HBM, advanced packaging.
Midstream: Servers, network equipment, data center construction.
Downstream: Cloud computing services, AI applications, enterprise intelligence.
In the future, AI value may not be concentrated solely in models and chips, but will gradually spread across the entire infrastructure system.
Beyond NVIDIA: Other Beneficiaries in the AI Industry Chain
In the past, discussions about AI investment almost always centered on NVIDIA. But as AI infrastructure enters an expansion phase, the market is seeking more areas of opportunity.
The first category is network infrastructure companies. As AI clusters grow larger, the demand for high-speed interconnects increases, raising the importance of network chips, switching devices, and optical communication technologies.
The second category is storage companies. HBM has become a critical component of AI chips, and storage manufacturers like SK Hynix, Samsung Electronics, and Micron are benefiting from the rising demand in AI data centers.
The third category is data center infrastructure companies, including server equipment providers, power management firms, cooling system manufacturers, and data center operators.
The fourth category is energy-related companies. As AI data centers expand over the long term, stable energy supply becomes essential, potentially driving increased investment in power infrastructure.
Therefore, future AI investment strategies may shift from focusing solely on chips to exploring opportunities across the entire industry chain.
Risks Facing AI Infrastructure Investment
Although the long-term trend for AI data centers is clear, investors should remain aware of several risks.
Capital expenditure risk. Global tech companies are pouring massive funds into AI infrastructure. If AI commercialization progresses slower than expected, it could affect the pace of corporate investment.
Supply and demand risk. The semiconductor, server, and data center industries are cyclical. When many companies expand simultaneously, temporary oversupply can occur.
Technology change risk. AI technology evolves rapidly, and computing architectures may shift in the future. If new technical approaches emerge, some infrastructure demand may be impacted.
Additionally, energy remains a long-term challenge. AI data centers require large amounts of stable power, but grid construction typically takes considerable time, which may limit the expansion speed of AI infrastructure in certain regions.
Thus, while AI infrastructure offers long-term opportunities, it is not simply a one-way growth market.
AI Data Center Competition Is Going Global
Building AI data centers has become a key part of global tech competition.
- The United States leads with top AI chip companies and cloud providers, serving as a major hub for AI infrastructure.
- South Korea, leveraging HBM storage technology, holds a crucial position in the AI hardware supply chain.
- Hong Kong and other Asian markets are also driving development in AI applications, cloud computing, and the broader tech industry.
The AI industry chain will not be concentrated in a single market, but will develop into a global collaborative system.
This means investors need to monitor AI industry changes from a global perspective.
