Rockchip RV1126 SoC Discontinued & RV1126B Replacement Launch

We hereby formally inform all valued customers that Rockchip RV1126—the widely used AI vision SoC—has been officially discontinued for over 1 year (since early 2025). To ensure uninterrupted supply and deliver enhanced performance, Rockchip has launched its upgraded successor: RV1126B, a high-performance 64-bit AI vision processor with stronger computing power, richer interfaces, and optimized energy efficiency.

As your trusted embedded solution partner, we have fully completed the technical adaptation and mass production of RV1126B-based motherboards. This article details the RV1126 vs RV1126B technical comparison, core advantages of RV1126B, and its key application scenarios to support your product upgrade and design transition.

1. RV1126 vs RV1126B: Core Technical Specifications Comparison

The RV1126B is a full-performance upgrade of the RV1126, with breakthroughs in CPU architecture, NPU computing power, ISP imaging, and peripheral interfaces. The detailed comparison is as follows:

2. Core Advantages of RV1126B

2.1 64-bit High-Efficiency CPU Architecture

The upgrade from 32-bit Cortex-A7 to 64-bit Cortex-A53 enables faster system response, smoother multi-tasking (e.g., video encoding + AI analysis + network transmission), and support for 4GB large memory, laying a solid foundation for complex application scenarios.

2.2 50% Higher AI Computing Power

With 3 TOPS NPU, RV1126B runs AI models (e.g., object detection, face recognition, anomaly analysis) 50% faster than RV1126. It supports mainstream frameworks (TensorFlow, PyTorch, Caffe) and INT8/INT16 hybrid operations, meeting the requirements of multi-model and high-precision AI applications.

2.3 AI-ISP + Multi-Camera Synchronous Processing

The built-in AI-ISP works independently of the NPU, implementing low-light enhancement (0.01Lux), HDR, 3DNR, and fisheye correction. It supports 4-channel MIPI-CSI synchronous input, enabling multi-camera stitching, panoramic monitoring, and stereo vision applications.

2.4 Rich High-Speed Interfaces

·  USB 3.0: 10Gbps ultra-fast transmission for high-definition video and large data storage.

·  Gigabit Ethernet: Stable high-speed network for real-time video streaming and remote management.

·  CAN FD: Industrial-grade bus for automotive and industrial control scenarios.

·  Integrated Audio Codec & RTC: Reduces peripheral BOM cost and simplifies design.

2.5 Low Power Consumption & Always-On Vision (AOV)

The optimized power architecture reduces typical power consumption to 2.8W, with AOV standby power as low as 1mW. It supports 7×24h abnormal sound (bark, glass breakage) wake-up and video-audio synchronous monitoring, suitable for low-power and long-term standby scenarios.

3. Key Application Scenarios of RV1126B

Thanks to its high performance, low power consumption, and rich interfaces, RV1126B is widely used in AIoT, smart security, industrial vision, smart home, and robotics fields. The main scenarios are as follows:

3.1 Smart Security & Surveillance

·  High-Definition IP Cameras: 4K@45fps encoding, AI intelligent analysis (motion detection, perimeter alarm, face recognition), suitable for home, store, warehouse, and urban monitoring.

·  Dual-Spectrum Cameras: Visible light + infrared fusion imaging, adapting to all-weather and harsh environments (rain, fog, total darkness).

·  AI PTZ Cameras: 360° panoramic monitoring, automatic tracking, and multi-point patrol, suitable for large-area scenarios (parks, construction sites).

3.2 Industrial Vision & Quality Inspection

·  ndustrial Cameras: 4-channel synchronous acquisition, high-precision defect detection (accuracy up to 99.5%), suitable for production line quality control (electronics, automotive, food).

·  Machine Vision Terminals: Supporting image recognition, size measurement, and barcode scanning, improving industrial automation efficiency.

3.3 Smart Home & IoT Devices

·  Smart Doorbells: Low-power AOV, real-time video intercom, human body induction, and remote alert.

·  Smart Home Hubs: Multi-sensor access, voice interaction, and home environment monitoring.

3.4 Robotics & Intelligent Terminals

·  Small Robots: Cleaning robots, desktop robots, and service robots, providing visual navigation, obstacle avoidance, and human-machine interaction capabilities.

·  Edge Computing Gateways: Data collection, AI analysis, and protocol conversion for IoT devices, realizing edge intelligence.

3.5 In-Vehicle & Industrial Control

·  In-Vehicle Vision: ADAS auxiliary driving, panoramic surround view, and driver status monitoring瑞芯微.

·  Industrial Control Terminals: CAN FD communication, multi-sensor access, and real-time monitoring, suitable for industrial automation and smart manufacturing.
