Overview
- Broadcom has begun shipping its next-generation Jericho4 networking ASIC and partners including Nokia and Accton have integrated it into high-performance routers to connect AI workloads across regional data centers.
- Jericho4 delivers up to 51.2 Tbps of lossless Ethernet fabric and uses high-bandwidth memory buffers to smooth traffic and support interconnection of over one million specialized processing units across multiple sites.
- The chip secures inter-site data transfers with line-rate MACsec encryption on every port, ensuring performance is maintained while protecting sensitive AI traffic from interception.
- Fabricated on TSMC’s 3-nanometer process, Jericho4 offers roughly 40% power reduction per bit to help contain energy costs in sprawling, power-hungry AI infrastructures.
- A single Jericho4 system can scale to 36,000 HyperPorts, consolidating four 800 GbE links into a 3.2 Tbps logical port and enabling interconnect bandwidths that can exceed 115 petabits per second.
