Out of beta and ready for data: 64-bit Raspberry Pi OS is here

(2022/02/03)


The Raspberry Pi Foundation has officially [1]released the 64-bit version of the Linux-based OS Formerly Known As [2]Raspbian .

A year and nine months after the [3]beta was [4]announced , the 64-bit version of the Raspberry Pi OS is ready for [5]download .

If you're still rocking an older Pi, be aware that the first few models had 32-bit-only CPUs. The new 64-bit OS won't run on a Pi 1, Pi 2, or Pi Zero.

Nearly two years is long enough to iron out quite a few wrinkles, but not all. The release notes describe a gotcha: you'll need to install a 32-bit version of Chromium to watch Netflix or Disney+. Since a lot of Pis are attached to TV sets for use as media players and streamers, that will be important to quite a few owners.

Using a 64-bit OS has some benefits, we're told: you can run app executables built for 64-bit Arm targets; and you get some performance boost from Arm's A64 instruction set. User-mode software can also use wider pointers, and potentially access a greater virtual space than the 3GB available in a 32-bit environment (a max of 4GB minus 1GB for the kernel). That said, most models of Pi have well under 4GB of physical RAM available, so this memory space issue is not as acute as one might fear.

As an aside, if you bought an 8GB Pi a while ago, 32-bit Linux can use Arm's [11]LPAE function to access over 4GB of physical memory.

If you use the camera module, you should stay with the [13]legacy version anyway as the newer [14]Debian Bullseye flavour of the OS doesn't support it.

Other 64-bit OSes are available: for instance, a 64-bit [15]version of Ubuntu for the Pi has been out for a while. ®

I’ve been running a 64bit Raspbian (CLI only version) on my 8GB Raspberry Pi 4 for several months now - with no trouble at all. It works very well but…

I think that the number one thing that the Pi needs is more compute. For cheap disposability, the Zero and 3 have got you covered. I’d like to see a more expensive, fast, Pi - perhaps even at the £100 price point.

But perhaps I’m a bit Pi obsessed. I love ‘em!

I'd just settle for being able to buy one

The capacity of human beings to bore one another seems to be vastly
greater than that of any other animals. Some of their most esteemed
inventions have no other apparent purpose, for example, the dinner party
of more than two, the epic poem, and the science of metaphysics.
