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.Ī more theoretical concern is that 32-bit pointers only allow you to address 4GB of memory. 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. Using arm6hf (Raspbian’s derivative of armhf with ARMv7-only instructions removed but floating-point instructions retained) provides us with an operating system which will run on every device we have ever manufactured, all the way back to 2011.īut we’ve come to realise that there are reasons to choose a 64-bit operating system over a 32-bit one.

ProductĪs you can see from the table above, it is easy to be confused about which products will support which Debian/Raspbian ports. However, 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.

From that point on, it has been possible to run a full 64-bit operating system on our flagship products, and many third-party operating systems are available. The ARMv8-A architecture, which encompasses the 64-bit AArch64 architecture and associated A64 instruction set, was first introduced into the Raspberry Pi line with Raspberry Pi 3 in 2016.
