That means for most applications, RAM is a non-issue.īut there are some cases, especially with servers or things like data processing, where one process could use more than 4 gigs, and in those cases, you should definitely use the 64-bit OS.Īnd for most people running a 64-bit OS won't cause any problems, except for maybe gobbling up a little extra RAM. That allows the full 8 gigs to be addressed, but only up to 4 gigabytes for any single process, like a Chromium browser tab. If you have less than 4 gigs of RAM, then memory isn't a huge concern and the 32-bit OS should run fine.īut 32-bit OSes can't address more than 4 gigabytes of RAM without some weird hacks like the one Pi OS uses, called Large Physical Address Extension. 64-bits, why?īut what are some reasons you might wanna run 64-bit Pi OS? Well, since I've been running it on all my Pis since spring last year, I'll tell you why I run it. The 64-bit release is only compatible with more recent Pis, like the Pi 3 and Pi 4 generations, as well as the Pi Zero 2 W. The 32-bit image is still listed first because it's still compatible with every Raspberry Pi ever made-including this ancient first generation model B!Īnd it probably won't go away for a while either, because Raspberry Pi still supports the Compute Module 1, which has the same processor, and that'll be supported until the end of 2026! Check out this video from leepspvideo for a guide on how to get it installed on your Pi. ![]() It's no longer hidden away in a crusty forum link, it's linked straight from their public downloads page and the Raspberry Pi Imager. Yesterday Raspberry Pi announced the 64-bit version is finally official. But almost all those problems have been ironed out now, and apparently it's time for the Raspberry Pi's 64-bit era. And the reason for that is it's actually branched directly off of Debian Linux and had a few growing pains. You had to kinda be 'in the know' to get it. Since May 2020, there's been a beta 64-bit version of Pi OS, but it wasn't intended for beginners, and was never linked from the main downloads page. And that's why it's taken years for Raspberry Pi OS to add an officially-supported 64-bit version, in addition to the 32-bit version they've had since the original Pi came out. The only catch right now is that the 64-bit of Chromium doesn't support Widevine DRM, so websites that require DRM (like Disney+ or Netflix) don't work - you'll need to install 32-bit Chromium instead.Well, not exactly. ![]() The switch to 64-bit means more applications and services can access the higher amounts of RAM on higher-tier Raspberry Pi boards (like the 8GB Raspberry Pi 4), and most people should see a performance boost. 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. Raspberry Pi said in a blog post ( via Ars Technica), "we have continued to build our Raspberry Pi OS releases on the 32-bit Raspbian platform, aiming to maximise compatibility between devices and to avoid customer confusion.
