Broadcom has also introduced the 400G OCP 3.0 adapter. The BCM57608 400G NIC is specifically designed for the demanding networking requirements of AI workloads, highlighted by highly high bandwidth utilization, intermittent data surges, and extended job durations.
The BCM57608 400G NIC leverages Broadcom’s 5nm process technology and is designed to fit into a PCIe Gen5 slot. This high-performance network interface card delivers an impressive 400 Gbps throughput, making it ideal for the high-scale, data-intensive environments typical of AI applications. Additionally, the NIC is optimized for low power consumption, ensuring efficiency in AI workloads that require sustained performance over long periods.
Power and Thermally Efficient Design
Broadcom’s new Ethernet adapter portfolio is the first in the industry built with 5nm process technology, enabling the most power-efficient and thermally-efficient design. These adapters can drive passive copper cables up to five meters or use ultra-low-power linear pluggable optics transceivers. Combined with Broadcom’s high-radix Ethernet switches, these adapters deliver higher rack density with mainstream air-cooling technology, making them ideal for modern data centers.
The demand for higher data transfer speeds in future AI networks is rapidly growing. Broadcom’s Ethernet adapters, equipped with a third-generation RoCE pipeline, low-latency congestion control technology, and innovative telemetry features, are designed to meet these needs. This portfolio is well-suited for AI infrastructure’s high-bandwidth, high-stress network environments.
Backed by Broadcom’s expertise in high-performance Ethernet solutions, this next-generation portfolio features the company’s sixth-generation-hardened NIC architecture. The adapter software is designed to be vendor-agnostic, supporting a broad ecosystem of CPUs, GPUs, PCIe, and Ethernet switches using open PCIe and Ethernet standards. As a founding member of the Ultra Ethernet Consortium, Broadcom underscores its commitment to a standards-based ecosystem.
Availability
The 400G PCIe Gen 5.0 Ethernet family (BCM57608) is now available from multiple server vendors and directly from Broadcom.
