X86 or X86_64?


Hi.

I am getting a new Shuttle XPC box with an Athlon 64 processor. I am wondering whether or not I should go with the 64-bit version of Fedora Core 4. I've been using the 32-bit version on my current machine without much trouble (except for not being able to turn on DMA with my DVD burner). I understand that the 32-bit version will run fine on Athlon 64. If I do decide to go to the X86_64 version, what pros and cons are there for me to consider?

TIA!
Dai

I'm running FC4-64 without too many problems. Definitely not ready for a system where stability is a requirement, but all the pieces (except a java plugin) seem to be there. Presumably 64-bit technology is the wave of the future ... If you're going to use a bleeding-edge distro anyway, seems to make sense to me to go with it.

CentOS 4.1 x86_64 might be good if you are looking for stability.

I'd say try x86_64 and if it doesn't work for you, fall back to the x86 version.

How about the Debian family on 64-bit, esp. AMD, processors:
  • Sarge
  • EDIT: 64-bit n/a in MEPIS
  • [Ku|U]buntu

We recently did an install for a guy w/ a Shuttle (sorry, don't know which mobo etc.) & the the decision, not mine I don't know 64-bit, was Kubuntu w/ the 32-bit kernel.

MEPIS does not have a 64 bit version. If you were running the 32 bit kernel on Kubuntu, then you were running an entirely 32 bit OS, even though it was running on a 64 bit processor. You can't have 64 bit apps running in userland on a 32 bit kernel.

You would actually need to install a 64 bit distro for you to be running a 64 bit Operating System. An example of this would be Kubuntu AMD64/EM64T, Debian Sarge AMD64 or Red Hat Enterprise Linux x86_64 edition.

Mac OS X is a good thing to compare to. The G5 is a 64 bit processor, but OS X is partly 64 bit, but mostly 32 bit.

I understand that. That's why I'm wondering whether to stick with the 32-bit version of FC4 or venture into the 64-bit version. I will be installing a lot of livna RPMs, so if they do have the 64-bit version of everything they have, then I should be pretty safe going to X86_64.

I too understand the difference between 32-bit & 64-bit OS's, what I was trying to ask is how do the Debian based ones perform. The "kid" who made the choice for our recent installee didn't think Kubuntu "64" was stable to put on someone else's box.

well, i am running suse 9.3 x86_64. i have no problems besides some of the little things that 32 bit would have too.

if ur running a x86_64 machine, then you can also run 32 bit apps.

the suse 9.3 os seems to be stable, i have had no crashes or unexpected events happen. , i also have been running 64 bit for about a year or so, and works great for me.

Thanks guys.

I decided to play safe and installed FC4 (32-bit) on my new Shuttle XPC box (SN85G w/ Athlon64 3700+).
