Broadcom Jericho 4 AI networking chip utilizes HBM technology
Thursday, December 25, 2025 at 02:19 PM
Broadcom's Jericho 4 AI networking chip incorporates High Bandwidth Memory (HBM), demonstrating that HBM applications are expanding beyond GPUs and AI ASICs into high-performance networking infrastructure.
Context
Broadcom is advancing its AI infrastructure roadmap by integrating High Bandwidth Memory into its next-generation Jericho 4 AI networking chips. While HBM has traditionally been reserved for high-performance GPUs and AI accelerators, its expansion into networking silicon is designed to eliminate data bottlenecks in large-scale AI fabrics. By incorporating HBM, the Jericho 4 AI achieves the massive memory bandwidth required to synchronize data across thousands of distributed processing units simultaneously.
This development is significant for investors as it expands the total addressable market for HBM manufacturers and solidifies Broadcom’s dominance in the AI back-end network. The Jericho 4 AI is expected to support massive scale-out architectures, enabling clusters of more than 32,000 GPUs with significantly reduced latency compared to previous generations. As AI models grow in complexity, the shift toward memory-integrated networking chips highlights a critical evolution in data center design, positioning Broadcom as a primary beneficiary of the ongoing infrastructure build-out.
