The semiconductor industry has officially entered the 2nm era. TSMC confirmed that its 2nm (N2) process entered volume production in Q4 2025, marking a major milestone in advanced node competition.

According to official data, the 2nm node introduces first-generation nanosheet transistor architecture, delivering significant improvements in both performance and power efficiency. Compared to previous nodes, it achieves approximately 10–15% speed gains at the same power level or 25–30% power reduction at the same performance.

This advancement is accelerating the evolution of AI infrastructure and high-performance computing systems. As chip performance increases, the demand for faster and more reliable data transmission within systems is also rising rapidly.

At the interconnect level, the PCIe 6.0 standard, developed by PCI-SIG, plays a critical role. The official specification delivers 64.0 GT/s data rates and up to 256 GB/s bandwidth (x16 configuration), while introducing PAM4 signaling and forward error correction (FEC) to support high-speed, low-latency communication.

This shift signals a broader industry transition—from pure chip performance competition to system-level connectivity performance.

For connector, cable, and wire harness manufacturers, this trend brings three major implications:

• Rising demand for high-speed interconnects in AI servers
• Stricter requirements for signal integrity and impedance control
• Increased importance of precision connectors and advanced materials

As hyperscale data centers and AI workloads continue to expand, the market for high-speed cables, connectors, and electronic components is expected to grow significantly, creating new opportunities across the electronics supply chain.
