Broadcom's Jericho4: Powering the Next Generation of AI Infrastructure with Unmatched Connectivity

-

Broadcom has taken a giant leap in AI infrastructure with the shipment of its Jericho4 Ethernet fabric router, a next-generation AI chip designed to revolutionize data center connectivity and massively scale AI model training. This cutting-edge platform is purpose-built to meet the growing demands of hyperscale cloud providers and AI computing environments, extending AI-scale Ethernet fabrics beyond the boundaries of individual data centers.

Jericho4: Engineered for Scale, Speed, and Security

  • Massive Scale: The Jericho4 supports interconnection of over one million processing units—including GPUs, CPUs, and other accelerators—spread across multiple data centers, surpassing traditional scaling limits.

  • Extended Reach: Designed to seamlessly link data centers up to 60 miles (96.5 km) apart, enabling distributed AI computing across geographically dispersed facilities.

  • Ultra-High Bandwidth: Delivering 51.2 Tbps of lossless, deep-buffered Ethernet throughput, Jericho4 ensures high-speed data flow essential for training ever larger and more complex AI models.

  • Advanced Congestion Management: The chip integrates high-bandwidth memory (HBM) to efficiently buffer traffic during network bottlenecks, optimizing data transfer and reducing latency.

  • Robust Security: Features full-speed MACsec encryption on every port, protecting sensitive data as it moves between data centers without compromising performance.

  • Energy Efficiency: Offers up to 40% power reduction per bit transferred, helping data center operators manage rising energy demands and operational costs.

  • Manufacturing Excellence: Built using TSMC’s advanced 3-nanometer process, combining cutting-edge semiconductor technology with Broadcom’s networking expertise for superior performance and reliability.

Why Jericho4 Matters for AI Infrastructure

As AI models grow exponentially in size and complexity, the infrastructure to support them faces unprecedented challenges. No single data center can meet the power, cooling, and space demands of these next-gen models alone. Jericho4 enables distributed AI computing by linking massive clusters across multiple sites, making high-performance, scalable AI training and inference possible on a global scale.

By delivering congestion-free, secure, and highly scalable connectivity, this chip boosts the efficiency of AI workloads at hyperscale companies like Microsoft, Amazon, Google, and others. Jericho4 complements Broadcom’s broader portfolio—including the Tomahawk 6 and Tomahawk Ultra chips—creating a comprehensive suite for high-performance computing and AI networking needs.

Conclusion: Paving the Future of AI with Innovative Connectivity

Broadcom’s Jericho4 chip marks a watershed moment in AI infrastructure, empowering the seamless, secure, and efficient scaling of AI models across vast, interconnected data centers. This innovation represents not just incremental hardware improvement, but a transformative step toward the AI-powered future.

“Innovation in connectivity fuels progress in AI—unlocking potential only possible when technology bridges distance with speed and security.”
