NVIDIA 900-53669-0000-000 | NVLink Bridge 3-Slot 2-Way, RTX A-Series Compatible

Q: What GPUs are compatible with this 3-slot NVLink bridge?
A: This bridge is compatible with NVIDIA RTX A6000, A5500, A5000, A4500, A40 professional GPUs, GeForce RTX 3090, and datacenter GPUs including A30, A100, A800, and H100. Both connected GPUs must be the same model. For A100 40GB/80GB configurations, three NVLink bridges are required for full connectivity.

Q: What is the bandwidth advantage of using NVLink over PCIe?
A: NVLink provides significantly higher bandwidth than traditional PCIe connections, delivering up to 112 GB/s of total bandwidth with a single bridge between two GPUs. This enables faster GPU-to-GPU data transfer, memory pooling across cards, and improved performance scaling for compute-intensive workloads like AI training, rendering, and simulation.

Q: What does '3-slot spacing' mean for this bridge?
A: The 3-slot spacing indicates that this bridge is designed for systems where the two connected GPUs are separated by 3 PCI-E slot positions. The physical bridge length is engineered to span this distance. It's essential to verify your system's GPU slot spacing matches before ordering—2-slot bridges are also available for tighter GPU configurations.

Q: Can I use this bridge to connect different GPU models?
A: No, both GPUs connected by the NVLink bridge must be identical models. You cannot mix different GPU models (for example, an RTX A6000 with an A5000, or an A-series card with a GeForce RTX 3090). The GPUs must also both support NVLink functionality.

Q: What workloads benefit most from NVLink connectivity?
A: NVLink excels in workloads requiring large memory capacity and high GPU-to-GPU data transfer rates, including AI model training with large datasets, real-time ray tracing and rendering, CAD/CAE simulation, deep learning inference, data science analytics, and professional visualization applications that exceed single-GPU memory capacity.
