NVIDIA Jetson Orin Nano 8 GB: A Compact Giant for Professionals and Enthusiasts

Overview of capabilities, performance, and practical applications in 2025

Introduction

The NVIDIA Jetson Orin Nano 8 GB is not just a graphics card but a fully functional compact computer on a module (SOM) designed for developers, engineers, and enthusiasts working with artificial intelligence, robotics, and edge computing. Although the device is not marketed as a gaming product, its architecture and functionality are noteworthy. In this article, we will explore what makes the Jetson Orin Nano unique, how it handles professional tasks, and why it could become your next tool for innovation.

1. Architecture and Key Features

Architecture: The Jetson Orin Nano is built on a hybrid platform using NVIDIA Ampere with elements of ARM Cortex-A78AE for the CPU and CUDA Cores for the GPU. This combination allows for efficient allocation of tasks between the central and graphics processors.

Process Technology: The chips are manufactured using 5nm technology from TSMC, ensuring high energy efficiency and compact size (module dimensions: 70×45 mm).

Unique Features:

- 3rd Generation Tensor Cores for accelerating AI inference (up to 40 TOPS).

- Support for CUDA, cuDNN, and TensorRT — key libraries for machine learning.

- Hardware video encoding/decoding (H.265, AV1) for 4K streaming.

It is notable that technologies like DLSS or RTX are not included here — the Jetson Orin Nano is focused on computations rather than game rendering.

2. Memory: Speed and Efficiency

Memory Type: The module uses LPDDR5 with a capacity of 8 GB and a bandwidth of 64 GB/s. This is sufficient for processing medium-sized neural network models (e.g., YOLOv8 or ResNet-50) and handling multiple HD video streams.

Impact on Performance:

- For AI tasks: 8 GB allow for model loading without constant data swapping, speeding up inference by 15-20% compared to the previous generation Jetson Nano.

- For rendering: In 3D applications (Blender, Unity), memory volume becomes a bottleneck when working with heavy scenes (>5 million polygons).

3. Gaming Performance: Realistic Expectations

The Jetson Orin Nano is not designed for gaming, but its GPU with 512 CUDA cores is theoretically capable of running lightweight projects. In tests conducted in 2025 (1080p resolution, low settings):

- CS2: ~45-50 FPS.

- Rocket League: ~55-60 FPS.

- Minecraft (with OptiFine): ~70 FPS.

Ray Tracing: Absent due to a lack of RT cores. In comparison, even a mobile RTX 3050 is four times faster in gaming.

Summary: The device is suitable only for undemanding projects or for streaming games via cloud services (GeForce NOW, Xbox Cloud).

4. Professional Tasks: Where Orin Nano Excels

Video Editing:

- Rendering a 4K video in DaVinci Resolve (H.265): ~2.5 minutes per minute of material (thanks to NVENC).

- Editing in Premiere Pro: Smooth timeline playback when working with 2-3 layers of HD video.

3D Modeling:

- Blender (Cycles): Rendering a scene with 1 million polygons takes ~12 minutes (compared to 6-7 minutes with RTX 3060).

- Support for OpenGL 4.6 and Vulkan 1.3 simplifies work with CAD applications (AutoCAD, SolidWorks).

Scientific Calculations:

- CUDA acceleration allows data processing in MATLAB or Python (NumPy, TensorFlow) to be 30% faster than on mid-range CPUs (Core i7-12700H).

- Example: Training a neural network on the MNIST dataset completes in ~15 minutes.

5. Power Consumption and Heat Output

TDP: 15 W — this is six times lower than that of the desktop RTX 4060 (115 W).

Cooling:

- Passive cooling solutions are adequate for basic tasks (temperature: 50-60°C).

- For prolonged loads (AI inference, rendering), active cooling (Noctua NF-A4x10 fans) is recommended.

Cases: The best options are compact solutions with ventilation holes (e.g., WaveShare Ice Tower).

6. Comparison with Competitors

- AMD Ryzen Embedded V3000: Better in multi-threaded CPU tasks but weaker in AI computations (no equivalent to Tensor Cores).

- Intel NUC 13 Pro (with Iris Xe): Wins in compatibility with Windows applications but falls short in energy efficiency.

- Raspberry Pi 5: Three times cheaper (~$80) but 5-7 times slower in GPU tasks.

Price: $499 (new module) — this is more expensive than consumer GPUs but cheaper than specialized industrial solutions.

7. Practical Tips

Power Supply: A 65 W adapter (e.g., Meanwell GST65A) is sufficient. Avoid cheap alternatives — voltage fluctuations can be harmful to the module.

Compatibility:

- OS: Ubuntu 22.04 LTS (optimized for JetPack 6.0).

- Platforms: Best performance when paired with peripherals via PCIe interface.

Drivers:

- Update JetPack SDK via NVIDIA SDK Manager.

- To work with ROS 2 (Robot Operating System), install the ros-humble-nvidia-orb package.

8. Pros and Cons

Pros:

- Energy efficiency: 15 W with performance comparable to desktop systems from 2020-2022.

- Out-of-the-box support for AI frameworks.

- Compactness and silent operation (in passive mode).

Cons:

- Limited memory capacity for complex AI models.

- Weak gaming performance.

- High price for non-professional use.

9. Final Conclusion: Who is the Jetson Orin Nano Suitable For?

This module is designed for:

- AI developers who value portability and low energy consumption.

- Robotics engineers building autonomous drones or manipulators.

- Edge computing enthusiasts experimenting with local data processing (e.g., smart cameras).

If you are looking for a GPU for gaming or high-level 3D rendering — consider the RTX 4060 or RX 7600. However, if your goal is to create smart devices "on the edge" of the network, the Jetson Orin Nano 8 GB will be the perfect choice.

Tensor Cores

Tensor Cores are specialized processing units designed specifically for deep learning, providing higher training and inference performance compared to FP32 training. They enable rapid computations in areas such as computer vision, natural language processing, speech recognition, text-to-speech conversion, and personalized recommendations. The two most notable applications of Tensor Cores are DLSS (Deep Learning Super Sampling) and AI Denoiser for noise reduction.

TMUs

Texture Mapping Units (TMUs) serve as components of the GPU, which are capable of rotating, scaling, and distorting binary images, and then placing them as textures onto any plane of a given 3D model. This process is called texture mapping.

Memory Bus

The memory bus width refers to the number of bits of data that the video memory can transfer within a single clock cycle. The larger the bus width, the greater the amount of data that can be transmitted instantaneously, making it one of the crucial parameters of video memory. The memory bandwidth is calculated as: Memory Bandwidth = Memory Frequency x Memory Bus Width / 8. Therefore, when the memory frequencies are similar, the memory bus width will determine the size of the memory bandwidth.

Bandwidth

Memory bandwidth refers to the data transfer rate between the graphics chip and the video memory. It is measured in bytes per second, and the formula to calculate it is: memory bandwidth = working frequency × memory bus width / 8 bits.

Miscellaneous

SM Count

Multiple Streaming Processors (SPs), along with other resources, form a Streaming Multiprocessor (SM), which is also referred to as a GPU's major core. These additional resources include components such as warp schedulers, registers, and shared memory. The SM can be considered the heart of the GPU, similar to a CPU core, with registers and shared memory being scarce resources within the SM.

Shading Units

The most fundamental processing unit is the Streaming Processor (SP), where specific instructions and tasks are executed. GPUs perform parallel computing, which means multiple SPs work simultaneously to process tasks.
