![]() ![]() It is worth noting that the 64-bit version of Chromium, installed by default, has no version of the WidevineCDM library, and therefore, it is not possible to play streaming media such as Netflix or Disney+. The 64-bit version of Raspberry Pi OS can be used on Raspberry Pi 3B, Raspberry Pi 3B+, Raspberry Pi 3A+, Raspberry Pi 4, Raspberry Pi 400, Raspberry Pi Compute Module 3 (CM3), Raspberry Pi Compute Module 3+ (CM3+), Raspberry Pi Compute Module 4 (CM4), and Raspberry Pi Zero 2 W. In the case of the full 64-bit Raspberry Pi OS, it will now allow access to up to 8GB of memory. ![]() Notice that this is the full version of the operating system that includes recommended software, but you can also access Lite versions from the repository. However, this version was not based on Raspbian, instead taking its user space. At first, you should download the latest archive file from the link above, which would be -raspios-buster-arm64.zip file at the time of writing. The 32-bit system allows addressing only 4GB of memory and makes use of the ARM Large Physical Address Extension (LPAE) to access up to 8GB of memory. On May 28, 2020, the Raspberry Pi Foundation announced a beta 64-bit version. The main benefit of a 64-bit OS over a 32-bit version is the RAM (the physical memory of the device). Beyond that there are some performance benefits intrinsic to the A64 instruction set: today, these are most visible in benchmarks, but the assumption is that these will feed through into real-world application performance in the future.” ![]() Compatibility is a key concern: many closed-source applications are only available for arm64, and open-source ones aren’t fully optimised for the armhf port. “But we’ve come to realise that there are reasons to choose a 64-bit operating system over a 32-bit one. “We have continued to build our Raspberry Pi OS releases on the 32-bit Raspbian platform, aiming to maximize compatibility between devices and to avoid customer confusion.,” Gordon Hollingworth, Raspberry Pi’s Director of Software Engineering, said in a blog post. Since then, it has been possible to run a full 64-bit OS ever however, the company chose to remain on a 32-bit version to focus on compatibility between devices. The ARMv8-A architecture, which encompasses the 64-bit AArch64 architecture and associated A64 instruction set, was first introduced by the Foundation into the Raspberry Pi line with Raspberry Pi 3 in 2016. ![]()
