Is there a noticeable performance benefit with RPi at 64bit?
- Mindwipe 6y ago
  There's the noticeable performance benefit that you can actually use the 8GB of RAM on the new model.

    There is an 8GB model? I thought the largest was 4GB (which I have)?

  Supposedly, yes. https://medium.com/@matteocroce/why-you-should-run-a-64-bit-os-on-your-raspberry-pi4-bd5290d48947 https://medium.com/@matteocroce/why-you-should-run-a-64-bit-...

    If real-world is anything like the graphs, it will be pretty good upgrade.

      I've been doing a few more informal tests (haven't had time to do a 1-2 day burn-in), and I've seen most CPU-intense operations are 3-5% faster (some more so) on the 64-bit release.

Debian aarch64 has been working well on the Raspberry Pi for a while now. Good to see Raspbian catching up.
- geerlingguy 6y ago
  Yeah I've seen more and more people switching to Ubuntu's 64 bit build just because there are a lot more arm64-compatible things floating around now than armv7. I'll be happy to not have to spend so much time compiling things for the 32-bit OS!

    Yep -- I just bought a Raspberry Pi 4 this past weekend and was surprised to learn that .NET Core wasn't supported until I realized Raspbian was 32-bit. I installed Ubuntu/arm64 and while I didn't realize it was a non-GUI OS that was fine and I was able to put .NET Core 3.1 and some small apps on it and all is well.

      8gb rpi4 just came out today.
    - tomfanning 6y ago
      Uh - I've been using Raspbian + .NET Core for ages. Works fine. pi@pi:~ $ uname -m armv7l
      - noarchy 6y ago
        Perhaps this is too much of a tangent, but why do people feel the need to type out "Uh" or "Um" in internet discussions? Are they trying to mimic the way they speak offline, because if so, it doesn't come across particularly well.

        It frames the intent of what they are about to "say". Before reading the technical details I already know that the author has a contrasting experience.

Proper ARM SBCL with threads yay
- tlavoie 6y ago
  Sweet, didn't think of this as one of the potential upgrades. I just installed Manjaro ARM (64-bit) on mine yesterday, along with SBCL. Sure enough, :SB-THREAD is there! Thanks for the tip.

Is migration from 32 bits possible?
- geerlingguy 6y ago
  In the comments on the announcement post, someone mentioned there would be a new post tomorrow covering more on the transition/upgrade, but it is supposedly possible using normal upgrade procedure (apt update then apt full-upgrade). At least that’s how I read it.

I’m strongly thinking of just migrating to Ubuntu server instead. This might give me pause

Finally! Does this mean ArchLinuxARM (ALARM) will also support 64 bits on RPi 4 soon?

With a $85 price tag I think it's moving away from its original premise of bringing cheap computing to the masses and especially students and tinkerers. Aside from that, I never liked the intimate relationship between Broadcomm and the RP Foundation.
