If you would like to increase the graphics processing power of your Raspberry Pi 5 you might be interested in an experiment carried out by Jeff Geerling. Who attached a second-hand graphics card in the form of a XFX AMD Radeon RX 460 4GB PCIe x16 he purchased on eBay. To a Raspberry Pi 5 using the Pineberry Pi adapter and help from the Coreforge repository on GitHub.
The Raspberry Pi 5 comes with built-in graphics that are fine for basic tasks. But if you want to do more complex work, like playing advanced games or running graphic-intensive programs, you can upgrade your setup with a used graphics card. This involves connecting the card to the Raspberry Pi’s PCI Express slot. It might sound tough, but with the right tools and some guidance, it’s a project you can handle.
To hook up your used graphics card to the Raspberry Pi 5, you’ll need the Pineberry Pi adapter. This little gadget is the bridge between your Raspberry Pi and the graphics card, making sure they work together smoothly. It’s made just for this kind of upgrade.

Once you’ve got the graphics card connected, you’ll see a big jump in how well your Raspberry Pi performs. Whether you’re using software that needs a lot of graphics power or playing games, an external graphics card will make everything run better than the standard graphics on the Raspberry Pi 5.
The main differences between the Raspberry Pi 5 standard graphics and those provided by the XFX AMD Radeon RX 460 4GB PCIe x16 include :
- Architecture:
- VideoCore VII GPU in Raspberry Pi 5: This is a mobile-oriented GPU designed for low power consumption and efficient handling of basic graphics tasks. It supports OpenGL ES 3.1 and Vulkan 1.2, indicating a good level of modern API support, especially for embedded systems.
- XFX AMD Radeon RX 460: A desktop-grade GPU, the RX 460 is based on AMD’s Polaris architecture. It is more powerful than the VideoCore VII, designed for higher-end graphics processing tasks, and supports full OpenGL and DirectX 12, catering to a wide range of gaming and professional applications.
- Performance:
- The VideoCore VII is suitable for basic graphical tasks, light gaming, and media playback. Its performance is tailored for the low-power, compact Raspberry Pi platform, emphasizing efficiency over raw power.
- The RX 460, with 4GB of dedicated VRAM and more robust hardware, is significantly more powerful. It can handle demanding games (albeit not at the highest settings), video editing, and 3D rendering with much greater ease than the VideoCore VII.
- Intended Use:
- The Raspberry Pi 5, with its VideoCore VII GPU, is aimed at hobbyist projects, educational purposes, and basic media and graphical tasks. It’s not intended for high-end gaming or professional-grade graphics work.
- The RX 460, on the other hand, is designed for budget-conscious PC gamers and users needing more substantial graphics capabilities for tasks like video editing or moderate gaming.
- Software Compatibility:
- Compatibility with software and games will vary significantly. The Raspberry Pi’s VideoCore VII will support basic games and applications that are compatible with OpenGL ES 3.1 and Vulkan 1.2.
- The RX 460 will have broader compatibility with PC games and professional software due to its support for more advanced graphics APIs and higher performance.
In summary, the VideoCore VII GPU in the Raspberry Pi 5 is a capable but modest performer, suitable for embedded systems and lightweight tasks. In contrast, the XFX AMD Radeon RX 460 is a more powerful, dedicated graphics card aimed at more demanding applications and gaming, offering higher performance and broader software compatibility. The choice between them depends largely on the specific requirements of the task at hand.
Upgrading Raspberry Pi graphics
But upgrading isn’t without its challenges. One issue is making sure you have the right drivers for the graphics card that will work with the Raspberry Pi’s operating system. Also, you have to think about cooling. The extra heat from the graphics card means you need a good cooling system to stop it from getting too hot and to keep it running well.
With the new graphics card, your Raspberry Pi 5 could even take the place of a regular desktop computer for some tasks. It can handle things like surfing the web, editing documents, and playing light games. This makes it a cost-effective choice for people who don’t need a super powerful computer.
To get the new hardware working, you’ll need to reconfigure the kernel. This is a fancy way of saying you need to tweak the operating system so it recognizes the graphics card. It might seem scary, but there’s plenty of help from the open-source community to walk you through this technical step.
By adding a pre-owned graphics card to your Raspberry Pi 5, you’re unlocking a whole new level of performance and flexibility. With some help from the open-source community and the right hardware, you can turn your Raspberry Pi into a much more powerful computer. Just remember to pay attention to driver compatibility and cooling, and you’ll be set for a great upgrade. Keep following for more updates that will keep making the Raspberry Pi better and better.
