Building on its AI network solutions, Broadcom Inc. has unveiled its portfolio of highly-scalable and low-power 400G PCIe Gen 5.0 Ethernet adapters, based on the 400G BCM57608 Ethernet controller, for AI data centers. These network adapters deliver an open standards-based Ethernet NIC and switching solution, claiming to resolve connectivity bottlenecks in AI clusters.
“At Broadcom, we recognize the significance of fostering a power-efficient and highly connected data center for AI ecosystem,” said Jas Tremblay, vice president and general manager of the Data Center Solutions Group, Broadcom, in a statement.

Broadcom claims the new high-performance portfolio is the industry’s first Ethernet adapter built with 5-nm process technology, enabling the most power and thermally efficient design in the market. The new BCM57608 family of adapters provides network connectivity using eight lanes of built-in SerDes, each supporting 100/50G PAM-4 and 10/25G NRZ. When combined with Broadcom’s high-radix Ethernet switches and its ability to drive passive copper cables up to five meters or ultra-low power linear pluggable optics transceivers, the adapter delivers higher rack density using mainstream air-cooling technology, reducing interconnect cost and power.
“End-to-end performance is critically important,” said Martin Hull, vice president, Systems and Platform Product Management, Arista, in a statement. “Broadcom’s 400G Network Adapter with high performance SerDes enables us to connect switches and servers using cost-effective cables or ultra-low-power linear drive optics.”
Targeting the growing demand for higher data transfer speeds required in future AI networks, Broadcom’s adapter portfolio provides a third-generation RDMA over converged Ethernet (RoCE) pipeline and low-latency congestion control technology. It is suited for high-bandwidth, high-stress network environments like AI infrastructures, providing scalability through features such as drop congestion notification, active latency management, high-density flat networks and hardware retransmission.
The Ethernet adapters feature Broadcom’s sixth generation-hardened NIC architecture. The adapter software, designed to be vendor agnostic, supports a broad ecosystem of CPUs, GPUs, PCIe and Ethernet switches using open PCIe and Ethernet standards, in support of the company’s objectives as a founding member of the Ultra Ethernet Consortium.
