NVLink – what is it?

NVLink is a high-speed interconnect technology developed by NVIDIA that enables direct data exchange between GPUs with bandwidth significantly higher than traditional interfaces such as PCIe. Architecturally, NVLink allows multiple GPUs to be combined into a single logical compute space with shared memory access, which is critical for scaling artificial intelligence and high-performance computing workloads.

In practical scenarios, NVIDIA NVLink is used to accelerate training and inference of large models, where data volume and the need for synchronization between GPUs create performance bottlenecks. The technology is deployed in data centers and AI clusters, providing low-latency data exchange, efficient scaling, and stable operation of distributed compute workloads.
