Raspberry Pi OS 64 bit now available in stable version

After a rather long beta period, the 64-bit version of the Raspberry Pi OS has finally reached its stable release. The announcement came via an official blog post from Gordon Holingworth, Chief Product Officer of Raspberry Pi Ltd. However, this new edition is not yet intended to replace the 32-bit version.

Originally made available as a beta in May 2020, the Raspberry Pi OS 64-bit has the same look and feel as the 32-bit version, but is capable to make better use of the latest Raspberry Pi models. From the Raspberry Pi 3 onwards (and a Raspberry Pi 2 model based on a downclocked Pi 3 SoC) the various Raspberry Pi models have been compatible with 64-bit software. To maintain compatibility between all variants, the Raspberry Pi has maintained a 32-bit operating system, but now that the balance has shifted more towards SoCs that support 64-bit, it was also necessary to build a suitable operating system.

This move ensures that new users can be up and running regardless of what Pi model they own. If you want to try the 64-bit image, it can be found in the Raspberry Pi OS (other) section.

At the moment, there is no support for Widevine DRM and that means it cannot play multimedia movies from sites like Disney + and Netflix. The current workaround, explained in the blog post, requires you to install the 32-bit Chromium browser. Hollingworth made it clear that performance between the two architectures is not an issue, saying “there is basically no downside to doing it.”

The Raspberry Pi 4 is the best place to start for DIY enthusiasts -at your place. Source: Raspberry Pi, Amazon The Raspberry Pi 4 and Compute Module 4 introduced a dilemma that hadn't existed before in the Pi ecosystem. There are models that have more than 4GB of RAM and typically a 32-bit OS cannot access more than 4GB. However, for those boards, the 32-bit Raspberry Pi OS still works around the limit to some extent.

“On the Raspberry Pi 4, we use the ARM Large Physical Address Extension (LPAE) to access up to 8GB of memory, subject to the constraint that each process is limited to 3GB access (we reserve the first 1GB of virtual address space for the kernel) ”- Hollingworth explained. For now, 32-bit and 64-bit will work in parallel, giving both new and old Raspberry Pi users the opportunity to squeeze the most out of the popular Single Board Computer.
