[22:01:03] <luxurien_french> Does someone could tell me how about the perfs differences between a dual Opteron and a X2 (same frequency) ?
[22:01:31] <luxurien_french> Could someone tell... *
[22:01:47] <Erle_> luxurien_french: Sorry I have no idea
[22:02:13] <luxurien_french> thank you Erle
[22:02:20] <Jerry507> I have owned neither, nor could I afford them
[22:03:00] <opus13> i thought they were essentially the same chip
[22:03:36] <luxurien_french> yes they are
[22:03:38] <opus13> the same cache and clock frequency on a common platform would yield the same results
[22:04:01] <luxurien_french> but a dual Opteron = 2 memory controllers
[22:04:19] <luxurien_french> with a X2, there is juste one memory controller
[22:05:52] <luxurien_french> i'm searching a reason to not buy a single dual core but a dual single core (then one day upgrade to dual dualcore)
[22:06:30] <AssKoala> luxurien_french - only 1 memory controller is used with the dual single core
[22:06:50] <AssKoala> itd be inefficient to use both, as synchronizing would be a bitch
[22:06:51] <luxurien_french> oh ?
[22:07:01] <AssKoala> more than 4 processors and they'll start using 2 controllers, etc
[22:07:15] <luxurien_french> well, okay.
[22:07:29] <AssKoala> dual core single socket is more efficient, especially because there's no bus to deal with for processor communication
[22:08:01] <Jerry507> AK is so cool
[22:08:04] <AssKoala> only issue is cache, and I think the X2's each core has their own L2 cache (good)
[22:08:11] <Jerry507> He knows stuff about hardware
[22:08:14] <luxurien_french> yes
[22:08:31] <AssKoala> Jerry507 - hey man, wtf is the point of programming if you dont know how what you're working on works
[22:08:41] <Jerry507> Um
[22:08:44] <Jerry507> Don't know
[22:08:50] <Jerry507> Don't do much programming
[22:08:54] <luxurien_french> okay, so with the K8 architecture, a dual socket is useful only for at least a dual dualcore
[22:09:02] <AssKoala> luxurien_french - yeah
[22:09:06] <luxurien_french> \o/
[22:09:14] <luxurien_french> thank you AK
[22:09:18] <AssKoala> dont get me wrong, you may get better mobos that are opteron instead of X2
[22:09:23] <AssKoala> but everything else equal
[22:10:05] <luxurien_french> yes i think too, but X2 and single socket mobos are cheaaaper :/
[22:10:11] <AssKoala> yeah, exactly
[22:10:19] <AssKoala> and with an nvidia chipset, they'll be as stable
