An overview of the Raspberry Pi 5 hardware lineup, covering RAM configurations from 1GB to 16GB, non-upgradable memory constraints, pricing, and OS resource consumption compared to desktop systems.
How much memory do you really need?
The Raspberry Pi's base operating system is based on Linux and is very lightweight. Unlike Windows or macOS, which often consume a lot of memory even when you're not doing anything, this system only requires a few hundred megabytes. This means you don't necessarily need a huge amount of memory for most tasks.
However, the cheaper 1GB version may struggle if you open three or four websites with lots of videos and images, as this can overwhelm it.
Options depending on use
If you plan to use the computer connected to a monitor for daily tasks and run multiple programs simultaneously, a version with at least 2GB of RAM offers the necessary comfort.
On the other hand, if you want to use the device without connecting it to a monitor, the basic 1GB version is an economical and perfectly functional solution for various tasks at home.
Prices and the most expensive models
The Raspberry Pi 5 comes in five different versions, ranging from 1GB to 16GB of RAM. Pricing starts at $45 for the base model, while the 8GB and 16GB models cost $175 and $305, respectively. In 2025, the company raised prices on all models due to ongoing memory component shortages.
Because of this cost, buying the more expensive versions often doesn't make sense. Regardless of the construction projects you may have in mind, for demanding tasks you can find ready-made used small desktop computers as an alternative, such as the Lenovo ThinkCentre and HP EliteDesk series.
