NVIDIA 900-53651-2500-000 | NVLink Bridge 2-Slot for Ampere GPUs

Q: What GPUs are compatible with this NVLink bridge?
A: This 2-slot NVLink bridge is compatible with NVIDIA RTX A6000, RTX A5500, RTX A5000, RTX A4500, and A40 GPUs based on the Ampere architecture. It connects two adjacent GPUs installed with no empty slots between them.

Q: What is the difference between 2-slot and 3-slot NVLink bridges?
A: The 2-slot bridge is designed for GPUs installed in adjacent PCIe slots with no empty slots between them. If you have one or more empty slots between your graphics cards, you need a 3-slot or 4-slot NVLink bridge instead.

Q: What performance benefits does NVLink provide?
A: NVLink enables high-speed GPU-to-GPU data transfer with significantly higher bandwidth than PCIe connections. It allows memory pooling across connected GPUs and provides lower latency for multi-GPU workloads including AI training, rendering, and simulation tasks.

Q: Can I use this bridge with NVIDIA A100 GPUs?
A: While the A100 supports NVLink connectivity, connecting two A100 GPUs requires three NVLink bridges due to the card's architecture. This single 2-slot bridge alone is not sufficient for A100 configurations.

Q: Is the NVLink bridge required for all dual-GPU setups?
A: No, the NVLink bridge is optional but recommended for workloads that benefit from direct GPU-to-GPU communication and memory pooling. GPUs can operate independently without NVLink, but applications optimized for NVLink will see performance improvements when connected.
