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