Four steps to AI on Jetson, each on two legs.

Jetson TX2 (2017): Embedded AI Jetson TX2 （2017）：嵌入式 AI

The release of the Jetson TX2 in 2017 marked a milestone in the development of embedded AI systems. Building on the success of its predecessors (TK1 and TX1), the TX2 introduced a more powerful and energy-efficient platform, making it suitable for real-time computer vision applications in edge devices.
2017 年发布的 Jetson TX2 标志着嵌入式 AI 系统发展的一个里程碑。在其前身（TK1 和 TX1）的成功基础上，TX2 引入了一个更强大、更节能的平台，使其适用于边缘设备中的实时计算机视觉应用。

The Jetson TX2 featured a Pascal GPU with 256 CUDA cores and a dual-core Denver 2 ARM CPU coupled with a quad-core ARM Cortex-A57. This architecture provided twice the performance of the TX1 while maintaining a similar power envelope. The TX2 found use cases in autonomous drones, robotics, and industrial automation, where real-time image processing and AI inference were essential. Its support for deep learning frameworks allowed developers to deploy AI models directly on the edge, reducing latency and improving time-sensitive performance.
Jetson TX2 采用具有 256 个 CUDA 内核的 Pascal GPU 和一个双核 Denver 2 ARM CPU 以及一个四核 ARM Cortex-A57。这种架构提供了 TX1 的两倍性能，同时保持了相似的功率包络。TX2 在自主无人机、机器人和工业自动化中找到了使用案例，在这些应用中，实时图像处理和 AI 推理是必不可少的。它对深度学习框架的支持使开发人员能够直接在边缘部署 AI 模型，从而减少延迟并提高时间敏感性能。

Jetson Nano (2019): AI at the Edge Jetson Nano （2019）：边缘 AI

The Jetson Nano, introduced in 2019, offered a low-cost platform for embedded computer vision. Designed for hobbyists, researchers, and developers working on budget-constrained projects, the Jetson Nano provided easy access to AI and machine learning tools.
Jetson Nano 于 2019 年推出，为嵌入式计算机视觉提供了一个低成本平台。Jetson Nano 专为从事预算受限项目的业余爱好者、研究人员和开发人员而设计，可轻松访问 AI 和机器学习工具。

Despite its affordable price, the Jetson Nano featured a 128-core Maxwell GPU and a quad-core ARM Cortex-A57 CPU, making it powerful enough to handle real-time image classification, object detection, and segmentation tasks. It supported popular AI frameworks such as TensorFlow and PyTorch, enabling the deployment of deep learning models in various applications. The Jetson Nano became popular in robotics, smart cameras, and educational projects. Its affordability and ease of use made it a platform of choice for developers looking to experiment with AI and computer vision on a smaller scale, without sacrificing performance.
尽管价格实惠，但 Jetson Nano 配备 128 核 Maxwell GPU 和四核 ARM Cortex-A57 CPU，使其功能强大，足以处理实时图像分类、对象检测和分割任务。它支持 TensorFlow 和 PyTorch 等流行的 AI 框架，从而支持在各种应用程序中部署深度学习模型。Jetson Nano 在机器人技术、智能相机和教育项目中广受欢迎。它的经济性和易用性使其成为希望在不牺牲性能的情况下在较小规模上试验 AI 和计算机视觉的开发人员的首选平台。

Jetson Xavier NX (2020): High-Performance AI in a Compact Form Jetson Xavier NX （2020）：紧凑的高性能 AI

In 2020, Nvidia introduced the Jetson Xavier NX, a compact yet powerful SBC designed to bridge the gap between the affordable Jetson Nano and the more robust Jetson AGX Xavier. The Xavier NX brought AI capabilities to edge devices that required a small footprint and low power consumption.
2020 年，Nvidia 推出了 Jetson Xavier NX，这是一款紧凑而强大的 SBC，旨在弥合价格实惠的 Jetson Nano 和更强大的 Jetson AGX Xavier 之间的差距。Xavier NX 为需要小尺寸和低功耗的边缘设备带来了 AI 功能。

The Jetson Xavier NX featured a Volta GPU with 384 CUDA cores and 48 Tensor Cores, providing up to 21 TOPS (trillions of operations per second) of AI performance. This made it suitable for demanding computer vision tasks, such as multi-camera processing, video analytics, and autonomous robotics.
