Cutting-Edge PCIe Technology Empowers Seamless Integration of Open Standards and Fabric Interconnects for AI Clusters

PALO ALTO, Calif., May 20, 2024 (GLOBE NEWSWIRE) – In a groundbreaking development for the AI networking landscape, Broadcom Inc. (NASDAQ: AVGO) has unveiled its latest portfolio of high-performance 400G PCIe Gen 5.0 Ethernet adapters. These adapters are designed to transform the data center ecosystem by addressing the ever-growing connectivity demands of AI data centers.

Pioneering Performance and Efficiency

Broadcom’s new 400G Ethernet adapters are set to revolutionize the AI infrastructure landscape with their scalable, high-performing, and low-power design. Built using advanced 5nm process technology, these adapters are the industry’s first of their kind, ensuring the most power and thermally efficient designs available. This innovation allows for superior integration and connectivity in AI clusters, which are becoming increasingly critical as AI workloads expand.

Jas Tremblay, vice president and general manager of the Data Center Solutions Group at Broadcom, highlighted the company’s commitment to advancing data center technology: “At Broadcom, we recognize the significance of fostering a power-efficient and highly connected data center for the AI ecosystem. Broadcom is prioritizing open standards and fostering collaboration with industry leaders to deliver the most extensive selection of high-performance connectivity solutions for AI infrastructure. Our 400G PCIe Gen 5.0 Ethernet adapters yet again underscore our commitment to enabling the network-centric AI infrastructure platform.”

Addressing Connectivity Bottlenecks

As AI data centers evolve, the need for higher data transfer speeds and more robust connectivity solutions becomes paramount. Broadcom’s new Ethernet adapters are specifically designed to meet these demands. They feature a third-generation RoCE (RDMA over Converged Ethernet) pipeline, low-latency congestion control technology, and innovative telemetry features. These advancements make them ideal for high-bandwidth, high-stress network environments typical of AI infrastructure.

Patrick Moorhead, CEO and chief analyst at Moor Insights and Strategy, emphasized the significance of these developments: “As the industry races to deliver generative AI at scale, the immense volumes of data that must be processed to train LLMs require even larger server clusters. Scalable high bandwidth, low latency connectivity is critical for maximizing the performance of these AI clusters. Ethernet presents a compelling case as the networking technology of choice for next generation AI workloads. The 400G NICs offered by Broadcom, built on its success in delivering Ethernet at scale, offer open connectivity at an attractive TCO for power-hungry AI applications.”

Innovations in AI Data Center Infrastructure

Broadcom’s latest portfolio represents a significant leap forward in Ethernet adapter technology. The 400G PCIe Gen 5.0 Ethernet adapters are equipped to handle passive copper cables up to five meters or ultra-low power linear pluggable optics transceivers. Coupled with Broadcom’s high-radix Ethernet switches, these adapters provide higher rack density using mainstream air-cooling technology, a crucial factor in modern data centers.

Broadcom’s long-term commitment to high-performance Ethernet solutions is evident in this new release, which builds on the company’s multi-decade heritage. This sixth-generation NIC architecture continues to fortify Broadcom’s leadership in Ethernet data center infrastructure, supporting a broad ecosystem of CPUs, GPUs, PCIe, and Ethernet switches through open standards.

Embracing Open Standards and Collaboration

The adapter software is designed to be vendor agnostic, emphasizing Broadcom’s dedication to an open, standards-based ecosystem. This approach aligns with Broadcom’s role as a founding member of the Ultra Ethernet Consortium, ensuring compatibility and seamless integration across various platforms and vendors.


The 400G PCIe Gen 5.0 Ethernet family (BCM57608) is now broadly available from multiple server vendors, as well as directly from Broadcom. For more information on the entire Ethernet adapters portfolio from Broadcom, please visit their official website.
