hello
is the intel centrino duo a 32bit or a 64bit processor?

http://www.intel.com/support/chipsets/sb/CS-022060.htm

that would seem like 64-bit. But on the other hand I found no site where it says it's 64-bit only (64-bit systems should always be able to run 32-bit operating systems, so..)

yeah but does that mean it is a 64bit processor?
because on intel's site it doesn't say anything.
the thing is, if i have a 64bit chip then i would like to install a 64bit system.
is there a way of knowing the chips speed?

"intel centrino duo" does not tell me what processor you have. Can you please post the exact model number. Mine is T7200 (laptop). If yours is a desktop then the number will probably start with an "E" instead of a "T" because it has a different power rating.

Intel (except Core 2 Duo, Centrino Core 2 Duo, or Xeon), AMD (except 64 or x2 dual-core), VIA C4, Apple MacBook Pro are all i386 (32 bit)


Intel Core 2 Duo, Centrino Core 2 Duo, and Xeon; AMD Athlon64/x2, Sempron64/x2, Duron64 are all x86_64 (64 bit processors that can run 32 or 64 bit applications)


If you want to be sure then pass me the processor model number....the label on your computer may say Centrino Duo but that doesn't tell you what you need to know. There are Intel Core Duo processors that are NOT 64 bit processors.
If your computer has Core "2" Duo then yes it is 64 bit. You may have a 64 bit- Core 2 Duo processor but the label on the outside of your computer may still just say "Centrino Duo."

i managed to do that and someone said if lm is written then it is 64 bit?

you mean x86 instead of i386(i386 is from 15 years ago)

AceofSpades: I took that directly off of the Fedora "how To" document at this link/:
http://docs.fedoraproject.org/instal...hich-arch.html
so if it's wrong or misleading then I must point the finger at them ...I think everyone got the point anyway.

OSC... Don't make me look up those codes. I'm too stupid and not to mention lazy. Just type 'cat /proc/cpuinfo' and the model name of your processor should ooozzz out in English.

Guessing...from the codes, I would say you have a XEON (Pentium 4)with EM64T support ...meaning yes it's a 64 bit proc... but if you list your entire 'cat /proc/cpuinfo' then I can tell you for sure.

they are taking about what architecture for their cds
heres a wikipeida article on x86 architecture http://en.wikipedia.org/wiki/X86

I don't doubt what you are saying. Yes, it's an article about what cd's to download BASED on your chips arch. Man you love to split hairs don't you! i386 x86 = the same thing when taken in the context of the discussion at hand.

i found out that intel core 1 is 32bit
intel core 2 is 64bit

so for all those lost, maybe this would help.
one question though,

if intel core 2 is 64 bit; then it is i686 or x86_64?
i suspect that i686 is intel while x86_64 is amd. right?

x86 is intel's brand of processers. i686 is the Pentium 3 and 4 family

Core 2 Duo, a lot of Xeons, Opteron 64s, Athlon 64s, Athlon 64 X2s, Athlon FX, and PPC 970 ("G5") are all 64-bit.

If it's a Core Duo, it's 32-bit. This is most likely the case; I think it would say if it was a Core 2 Duo.

PS: Centrino is a framework of sorts, like AMD Live! and Intel Viiv. Centrino denotes wireless cards, CPUs, and a number of other devices.
