RK3399

The RK3399 is a high-performance, hexa-core processor from Rockchip, designed for AI, IoT, and multimedia applications. It features:
- Dual-core Cortex-A72 (up to 1.8GHz) + Quad-core Cortex-A53 (up to 1.4GHz) for balanced power and efficiency.
- ARM Mali-T860 MP4 GPU supporting 4K H.265/H.264 video decoding.
- Dual-channel 4GB LPDDR4 RAM support and multiple storage interfaces (eMMC, SDIO).
- Rich connectivity: USB 3.0/2.0, PCIe, HDMI 2.0, MIPI-DSI/CSI, and Gigabit Ethernet.
- AI acceleration via NPU (in some variants) and compatibility with TensorFlow Lite.
Commonly used in single-board computers (e.g., Rock Pi 4, NanoPC-T4), AI edge devices, and embedded systems, the RK3399 balances performance and power efficiency for demanding applications.

The RK3399's equivalents include:
- Qualcomm Snapdragon 820/821 (similar CPU/GPU performance)
- MediaTek Helio X20/X25 (decacore, mid-range)
- NVIDIA Tegra X1 (higher GPU power)
- Samsung Exynos 8890 (flagship-level, octa-core)
- HiSilicon Kirin 960 (comparable CPU, weaker GPU)
These chips offer similar processing power, GPU performance, or use cases (e.g., tablets, AIO PCs). The RK3399 excels in cost-efficiency for Linux/Android SBCs like Rock Pi 4 or Tinker Board 2.

The RK3399 is a hexa-core SoC by Rockchip with a 314-pin TFQFP package. Key functions include:
- Dual ARM Cortex-A72 + Quad Cortex-A53 (big.LITTLE)
- ARM Mali-T860MP4 GPU
- Dual-channel 64-bit LPDDR3/LPDDR4/DDR3/DDR4 support
- 4K VP9/H.265/H.264 video decoding
- HDMI 2.0, eDP 1.3, MIPI-DSI/CSI display interfaces
- USB 3.0/2.0, PCIe, Gigabit Ethernet
- I2C, SPI, UART, PWM, GPIOs for peripherals
Pins are allocated for power, memory, multimedia, and connectivity, making it suitable for tablets, SBCs (e.g., Rock Pi 4), and embedded systems.

The RK3399 is manufactured by Rockchip, a Chinese semiconductor company based in Fuzhou, Fujian. Founded in 2001, Rockchip specializes in designing system-on-chip (SoC) solutions for consumer electronics, including tablets, smart TVs, IoT devices, and single-board computers (like the Rock Pi 4).
The RK3399 is a high-performance, hexa-core ARM processor (dual Cortex-A72 + quad Cortex-A53) with strong GPU capabilities (Mali-T860), targeting mid-range to high-end embedded systems. Rockchip is known for cost-effective, power-efficient chips but lacks the brand recognition of larger players like Qualcomm or MediaTek.
Rockchip collaborates with companies like Google (for Chromebooks) and Pine64 (for development boards), positioning itself as a key player in China’s chip industry.

The Rockchip RK3399 is a versatile SoC used in:
1. Single-Board Computers (SBCs) – Like Rock Pi 4 and NanoPC-T4.
2. Mini PCs & TV Boxes – For media playback and light computing.
3. Embedded Systems – Industrial automation, IoT gateways.
4. Robotics & Drones – AI and vision processing.
5. Edge AI & Vision – Supports TensorFlow Lite, object detection.
6. Gaming & AR/VR – Handheld consoles and lightweight VR.
7. Digital Signage & Kiosks – 4K display output.
Its dual-core Cortex-A72 + quad-core A53 and Mali-T860 GPU make it suitable for performance-demanding embedded applications.

The RK3399 is available in a TFBGA (Thin Fine-Pitch Ball Grid Array) package with 576 pins. It measures 23 mm × 23 mm and supports dual-channel memory, multiple display outputs, and high-speed interfaces like USB 3.0 and PCIe. The package is designed for compact, high-performance applications such as single-board computers and embedded systems.
