What Is Edge AI Hardware?
Edge AI hardware refers to computing platforms designed to run AI tasks locally on devices, enabling real-time processing, lower latency, and reduced bandwidth by handling data where it is generated instead of in the cloud. These platforms combine general-purpose processors (CPU/MCU) with accelerators like GPUs, NPUs, TPUs, FPGAs, or ASICs to speed up deep learning inference under tight power and thermal constraints.
Key Features & Benefits of Edge AI Hardware
- Low latency: Local inference minimizes cloud delays, enabling timely response for vision, control, and safety-critical systems.
- Power efficiency: Operates under strict power and thermal limits, making performance per watt a key design metric.
- Heterogeneous computing: Combines CPUs, NPUs, GPUs, and DSPs for efficient mixed workloads.
- Deployment Flexibility: Supports multi-device and multi-node deployments, with flexible form factors for easy integration.
- Connectivity independence: Works offline or intermittently, preventing downtime in critical applications.
- On-device privacy and security: Keeps sensitive data local, reducing exposure and easing compliance
Common Types of Edge AI Hardware
- Chip-Level
Core computing units, including microcontrollers (MCUs) for low-power, real-time control tasks; SoCs for integrated heterogeneous AI and general-purpose processing; GPUs and VPUs for vision and video analytics; and specialized NPUs, FPGAs, and ASICs for high-performance, low-latency workloads in robotics, autonomous driving, and other edge applications.
- Module-Level
Development-ready AI SoMs (compact compute modules with AI-enabled SoCs) and add-on AI accelerator modules (AI coprocessors that offload intensive neural network computation from the CPU, typically via M.2/PCIe), simplifying system design and enabling dedicated AI processing in industrial and embedded devices.
- System-Level
Complete edge systems that integrate AI via on-board or plug-in AI accelerators, including AI SBCs, Box PCs, gateways, AI cameras and smart devices, supporting low-latency, on-device AI inferencing with improved data privacy for industrial, retail, smart city, and IoT applications.
Edge vs Cloud AI Hardware
The main difference lies in where computation runs and how hardware is optimized.
