SmartNIC
An intelligent network interface card that offloads networking, security, and data processing tasks from the main CPU, improving efficiency in AI data center workloads.
SmartNICs handle tasks like encryption, compression, and network virtualization that would otherwise consume CPU resources needed for AI processing. NVIDIA's BlueField DPU (data processing unit) is the leading SmartNIC for AI data centers, offloading infrastructure tasks to free GPU and CPU resources for AI workloads. SmartNICs can improve AI cluster efficiency by 15-20% by handling the network overhead of distributed training. The market is projected to reach $8 billion by 2027 as data centers optimize every component for AI performance.
