Hi everybody,
I want to install Gentoo on a machine with an Intel Core 2 Quad 2.4 GHz. Which architecture should I install?
Thank you in advance for your anwers.

First of all, this has been answer about a hunderd times... just search for 'x86 amd64 core2'
seconds, it somewhat depends on how much ram you have (hint: 4GB), and for what you want to use your system (hint: number crunching)
cheers

Well, I searched for the name of the processor and got no result, so I asked.
I have 4 GB of RAM, and I don't care about flash, if that's what you mean.

You'll want amd64.

Aha! I was just about to suggest IA64, but thats Itanium isn't it?
I have been in AMD land so long I have forgotten about intel. So is it right then that the AMD64 architecture also cover the Intel dual core 64 bit CPUs?

Yes.
It is just the arch name, the same happened in the past. For example, i686 is an Intel name, but not only intel processors were considered i686 processors, for example, the i686 in the intel worl'd was pII or p-pro, but the k6-2 from amd was also an i686 cpu. Since amd was the first cpu to implement this concrete architecture, it makes perfect sense that the arch is named amd64. The old intel 64 bit cpu's are different (IA64) and are not pc compatible. New intels use an architecture that aims to be compatible with amd64. |

Let's make it amd64 then.
Thank you all!

Actually, the AMD k6 is not an i686, it's an i586. As far as I can tell, the single essential difference between i586 and i686 is the CMOV instruction. It's easy to check, because it's one of the flags in /proc/cpuinfo. The earlier Via processors were also i586, but they added CMOV to more recent models, to make them i686.
Probably not relevant to the current discussion, but just a clarification.

I don't know if the cmov instruction was introduced on any of k6-2 or k6-3 series, if at all (I was talking about those, and not the first k6, I knew those are just i586). Anyway, it doesn't really matter. Change i686 by i586 and the whole point of the thread is still valid.
Thanks for the info, though  |
