Broadcom P1400GD Thor 2 High-Performance Single-Port 400G PCIe Ethernet Network Adapter - PCIe 5.0 x16 low profile - 400 Gigabit CM957608-P1400GDF00

Broadcom P1400GD — Single-Port 400G PCIe 5.0 x16 Ethernet NIC for AI/ML, Cloud & HPC Data Centers

Built on Broadcom's industry-leading scalable 400G Ethernet controller architecture, the Broadcom P1400GD (BCM957608-P1400GDF00) is a single-port 400 Gigabit Ethernet Network Interface Card engineered for the most demanding server networking environments. Whether you're scaling AI/ML training infrastructure, deploying hyperscale cloud networks, accelerating high-performance computing (HPC) clusters, or building high-throughput NVMe-over-Fabrics storage networks, the P1400GD delivers the bandwidth, latency, and security capabilities your data center demands.

Hardware-Accelerated RoCEv2 RDMA for Ultra-Low Latency

The P1400GD features fourth-generation, standards-based RDMA over Converged Ethernet (RoCEv2) with hardware-based congestion control, delivering the lowest latency RDMA performance in real-world scenarios. Broadcom's proprietary Switch Aware Rate Adjustment (SARA) and Drop Congestion Notification (DCN) technologies simplify large-scale RoCE deployments and eliminate the complexity that typically comes with RDMA at scale — making the P1400GD the ideal 400G RDMA NIC for distributed AI training, GPU-direct storage, and MPI-based HPC workloads.

TruFlow™ Offloads & Inline Encryption — Free Your CPU

With TruFlow™ 400G hardware flow offload, TLS 1.3 and QUIC inline encryption, and advanced transmit pacing all handled directly in silicon, the P1400GD dramatically reduces CPU overhead. Network-intensive operations are offloaded to dedicated hardware engines, freeing host CPU cores for application workloads, increasing virtual machine density, and reducing total cost of ownership across the entire server fleet.

Zero-Trust Security with Silicon Root of Trust

Security is built into the P1400GD at the silicon level. Broadcom's Silicon Root of Trust anchors a full chain of trust from hardware through firmware, with SPDM-compliant attestation allowing data center operators to cryptographically verify the authenticity and integrity of every deployed adapter. Secure boot protection and hardware attestation make the P1400GD compliant with zero-trust architecture frameworks and the most stringent enterprise security policies.

Designed for AI/ML GPU Server Integration

The P1400GD supports NIC partitioning with up to 16 physical functions (PFs) and is engineered for seamless integration with Broadcom's PCIe Gen 5 switch ecosystem in GPU-based AI and machine learning server platforms. Its low-profile, half-length PCIe form factor fits in standard 1U and 2U servers as well as high-density GPU node configurations.
