Where Is the AI Infrastructure Industry Chain Stuck?

The AI infrastructure (AI Infra) industry chain is facing unprecedented systemic bottlenecks, despite the rapid emergence of applications like DeepSeek and Seedance 2.0. The surge in global computing demand has exposed critical constraints across multiple layers of the supply chain—from core manufacturing equipment and data center cabling to specialty materials and cleanroom facilities. Key challenges include four major "walls": - **Memory Wall**: High-bandwidth memory (HBM) and DRAM face structural shortages as AI inference demand outpaces training, with new capacity not expected until 2027. - **Bandwidth Wall**: Data transfer speeds lag behind computing power, causing multi-level bottlenecks in-chip, between chips, and across data centers. - **Compute Wall**: Advanced chip manufacturing, reliant on EUV lithography and monopolized by ASML, remains the fundamental constraint, with supply chain fragility affecting production. - **Power Wall**: While energy demand from data centers is rising, power supply is a solvable near-term challenge through diversified energy infrastructure. Expansion is further hindered by shortages in testing equipment, IC substrates (critical for GPUs and seeing price hikes over 30%), specialty materials like low-CTE glass fiber, and high-end cleanroom facilities. Connection technologies are evolving, with copper cables resurging for short-range links due to cost and latency advantages, while optical solutions dominate long-range scenarios. Innovations like hollow-core fiber and advanced PCB technologies (e.g., glass substrates, mSAP) are emerging to meet bandwidth needs. In summary, AI Infra bottlenecks are multidimensional, spanning compute, memory, bandwidth, power, and supply chain logistics. Advanced chip manufacturing remains the core constraint, while substrate, material, and equipment shortages present immediate challenges. The industry is moving toward hybrid copper-optical solutions and accelerated domestic supply chain development.
