PNY NVIDIA NVLink Bridge Board, 4-way

The PNY NVIDIA NVLink Bridge Board 4-Way (NVLBOARD-4WAY-SB) is a hardware interconnect for multi-GPU workstations and servers. It provides a high-bandwidth, low-latency path for direct communication between graphics processors, bypassing the standard PCIe bus. Designed for 4-way configurations, it allows four compatible NVIDIA GPUs to function as a single unit for demanding workloads, such as large-scale simulations or high-end rendering. This architecture accelerates data transfer between GPUs, which is required for applications that rely on direct peer-to-peer communication.

This bridge is a passive interconnect that requires no external cooling or power. It is used in GPU-based servers, particularly for AI development. Its 4-way design aligns with the specific layout of 4-GPU server nodes, ensuring efficient data throughput in systems built for multi-GPU scaling. Professionals use this bridge to maintain synchronization across high-density hardware clusters.

• PCIe Gen 5 support: ensures compatibility with the high transfer rates of current motherboard architectures.
• 365g unit weight: provides a rigid physical connection to maintain GPU alignment within the chassis.
• Hopper and H200 NVL support: verified for 4-way data centre configurations.
• Direct memory access: allows GPUs to share memory resources without routing traffic through the CPU.
• Dedicated NVLink connectors: uses specialized pins to maintain signal integrity across all four connected GPUs.
• Low-latency performance: reduces data bottlenecks by providing a direct communication path between GPU cores.
