The Raspberry Pi has been able to support 64-bit operating systems for some time, so no new hardware upgrades are necessary to take advantage of the new OS edition. This isn’t the first 64-bit operating system for the Pi as there are plenty of third party options available, but it is the first official 64-bit OS to come from the Raspberry Pi Foundation.
According to the official Raspberry Pi website, the following Pi models are officially supported:
- Raspberry Pi 3B
- Raspberry Pi 3B+
- Raspberry Pi 3A+
- Raspberry Pi 4
- Raspberry Pi 400
- Raspberry Pi CM3
- Raspberry Pi CM3+
- Raspberry Pi CM4
- Raspberry Pi Zero 2 W
Gordon elaborated in the comments about the repository details, explaining that the 32-bit Raspberry Pi OS upstream is Raspbian while the new 64-bit version’s upstream is Debian. However, both have been modified with tools, features, and a design catered to the Raspberry Pi, making it the OS we know.
