‘Copper’s time is up’: Nvidia, AMD and TSMC have invested millions in a startup that may hold the key to faster chip connectivity to quench AI’s thirst for bytes


  • Ayar Labs is valued at $1 billion and is at the forefront of silicon photonics
  • The company has raised money from a wave of investors, including Intel and Global Foundries
  • It says copper has almost reached its physical limits for chip interconnects, and now it wants to see what’s next

The rapid expansion of AI has brought unprecedented challenges to data movement within AI infrastructure, especially for traditional copper connections, which were once sufficient for data transfer but are now struggling to meet the demands of increasingly complex AI models.

This bottleneck has led to inefficiencies in compute performance, power consumption, and overall scalability. Addressing these issues is critical as AI adoption continues to grow across industries, requiring a more efficient solution for managing the massive data flows required for AI training and inference.
