🧪 Performance Benchmarks
Jetson Nano’s performance truly shines in AI applications. While it may not match desktop GPUs like RTX cards in raw power, it offers enough capability for real-time inference, even on complex models like MobileNet, YOLO, and ResNet.
AI Task Performance (FPS)
MobileNet (Classification) ~20–25 FPS
Tiny YOLO (Object Detection) ~8–12 FPS
Face Recognition (OpenCV + DNN) ~10 FPS
Pose Estimation (OpenPose Lite) ~5 FPS
These numbers, achieved with optimized TensorRT models, are impressive for a 5–10W device. The ability to run these tasks locally, without cloud dependency, is key for security, latency, and cost-sensitive applications.
