The Raspberry Pi is a small, single-board computer that has become a popular choice for people who want to learn about programming, build DIY projects, or experiment with technology. One of the key factors to consider when choosing a Raspberry Pi is the amount of RAM (Random Access Memory) it has. In this blog post, we will help you understand the different RAM options available for the Raspberry Pi 5 and 4 and guide you in selecting the best one for your needs. Disclaimer: At the time of writing, the Raspberry Pi 5 16Gb option has not been released, but seems to be confirmed, so we are including this option as a hypothetical option without having any concrete tests done with it.
What is a Raspberry Pi?
A Raspberry Pi is a credit card-sized computer that can be used for a wide range of applications. It has a processor, memory, and input/output ports, allowing it to run various operating systems and software. The Raspberry Pi is often used for:
- Learning to code
- Building DIY projects, such as robots, home automation systems, and media centers
- Running retro games and emulators
- Hosting websites and web applications
- Conducting scientific research
Raspberry Pi 5 RAM Options
The Raspberry Pi 5 is available with three RAM options: 2GB, 4GB, and 8GB, with a 16GB option coming soon. Each option offers a different level of performance and capabilities.
- 2GB RAM
- Best for: Basic computing, simple projects, and beginners
- What you can do:
- Basic tasks like web browsing, writing documents, and running lightweight applications.
- Simple electronics projects, like controlling LED lights, temperature sensors, or building a small weather station.
- Media centers using software like Kodi to stream videos and music.
- Example project: You can build a basic home automation system to control lights or check sensors using the 2GB model. It’s also ideal for creating a retro gaming console to play classic games with emulation software.
- 4GB RAM
- Best for: Intermediate users who need more power for multitasking or slightly more complex projects.
- What you can do:
- Run multiple applications simultaneously, like a web browser, word processor, and media player without slowing down.
- More demanding electronics projects, such as building a security camera system with live video streaming, or managing multiple sensors and actuators.
- Learning to code with programming languages like Python and JavaScript while running other applications.
- Example project: With 4GB of RAM, you can build a smart mirror that displays live weather updates, your calendar, news, and more—perfect for multitasking and handling multiple data streams.
- 8GB RAM
- Best for: Power users, developers, and those working on demanding projects.
- What you can do:
- Run a home server for managing files, hosting a website, or acting as a media server for your home.
- AI and machine learning projects, like running TensorFlow Lite for image recognition, object detection, or facial recognition.
- Virtualization and containerized applications, using tools like Docker to run multiple virtual environments on a single device.
- Example project: With 8GB of RAM, you can create a network-attached storage (NAS) system to store and manage large amounts of data from multiple devices, stream media, or run cloud-based applications in your home.
- 16GB RAM (Raspberry Pi 5)
- Best for: Heavy computing tasks, AI, and intensive programming projects.
- What you can do:
- AI and machine learning at a higher level, such as real-time video processing and advanced neural networks.
- 3D rendering, CAD software, and other highly demanding applications.
- Complex server applications such as managing large-scale databases, handling numerous simultaneous connections, or hosting virtualized environments.
- Example project: You could build a mini-AI research station using the Raspberry Pi 5’s 16GB model, running complex simulations, training AI models, or using the Pi as a deep learning inference machine.
Which RAM Option is Best for Using with an AI Kit?
If you’re planning on using a Raspberry Pi for AI-based projects, such as image recognition, natural language processing, or machine learning, 8GB or 16GB RAM is your best bet. AI kits like the Google AIY Kit or NVIDIA Jetson Nano can push the Raspberry Pi’s processing capabilities to the limit, especially if you’re using frameworks like TensorFlow, PyTorch, or OpenCV. These frameworks require substantial memory to handle data processing and real-time inference tasks.
- 8GB RAM: Suitable for AI kits if you’re working on moderately complex projects, like recognizing objects in images or creating a smart assistant.
- 16GB RAM: Ideal for intensive AI tasks, such as real-time video analysis, running multiple AI models simultaneously, or training more complex neural networks.

Conclusion: Which Raspberry Pi RAM Option Should You Choose?
The amount of RAM you need largely depends on the complexity of the projects you plan to work on. Here’s a quick summary:
- 2GB RAM: Great for beginners and basic projects like simple automation, web browsing, and media streaming. It’s affordable and perfect if you’re just getting started.
- 4GB RAM: A balanced option for those who want to experiment with more demanding tasks like running multiple programs, intermediate coding, or building a smart home system.
- 8GB RAM: Ideal for power users who want to dive into AI, machine learning, or run a home server. It’s also a great option for developers who need more memory for multitasking.
- 16GB RAM: The go-to choice for anyone working on advanced AI, research, or extremely resource-intensive projects. If you’re planning on pushing the Raspberry Pi to its limits, this is the model for you.
If you’re unsure which one to get, 4GB is a safe middle ground. It offers enough memory for most hobbyist projects without breaking the bank. However, if you’re diving into AI or advanced development, 8GB or 16GB will serve you best.
