In this write-up, we will explore the installation method of the 64-bit version of the Raspberry Pi operating system on the Raspberry Pi 4.
What is a 64 bit Raspberry Pi OS
We know that the Raspberry Pi is a single-board computer that contains RAM and a processor and we also know that there are two types of computer processors known as 32-bit and 64-bit processors. The Raspberry Pi foundation also released both types of Raspberry Pi operating systems which are known as 32-bit Raspberry Pi OS and 64-bit Raspberry Pi OS.
The 64 bit Raspberry Pi OS has a faster processing speed as compared to the 32-bit and it has more security features against viruses that can harm the operating system.
How to download the 64-bit Raspberry Pi OS
To download the 64-bit Raspberry Pi OS, we will go to the official website of the Raspberry Pi and download its image file of 64-bit from there. Once the image file of 64-bit Raspberry Pi OS has been downloaded, write it on the SD card using the Raspberry Pi imager. (if you do not have the Raspberry Pi imager, it can be downloaded from its official website).
How to write the image file of 64-bit Raspberry Pi OS
To write the image file of 64-bit Raspberry Pi, launch the Raspberry Pi imager on the computer and choose the OS by going to the path of the downloaded image file of 64-bit Raspberry Pi OS:
Choose the SD card/USB on which you want to write the image file of 64-bit Raspberry Pi OS and click on the “Write” button:
A notification will appear on the screen to remove the card as the image has successfully written on the SD card.
After this insert the SD card/USB in the Raspberry Pi 4 and turn on the power of the Raspberry Pi 4.
How to tell if Raspberry Pi OS is 32-bit or 64-bit
To check whether the Raspberry Pi OS is 32-bit or 64-bit, simply open the terminal of the Raspberry Pi and run the following command:
If the output shows you the “arm71” it means the installed operating system is 32-bit and if it shows you the “aarch64” which is displaying in our case, it means you are using the 64-bit Raspberry Pi operating system.
What is the comparison of 64-bit vs 32-bit Raspberry Pi OS
All the specifications of both Raspberry Pi operating systems are the same, the major difference is in Kernel, as 32-bit Raspberry Pi OS supports the 5.10.92-v71+ (armv71) and the 64-bit Raspberry Pi OS supports the 5.10.92-v8+ (aarch64). Due to the improved architecture, the performance of the 64-bit Raspberry Pi OS is greater than the 32-bit Raspberry Pi OS.
The 64-bit version of the Raspberry Pi OS has been launched recently in 2021 and can be used on the Raspberry Pi devices above the Raspberry Pi 3 models. The WidevineCDM service is not included in the 64-bit Raspberry Pi OS due to which the users cannot stream Disney+ and Netflix. In this write-up, we have learned the installation method of the 64 bit Raspberry Pi OS on the Raspberry Pi 4.
