Two Dual-core AMD 3800+X processors
3 Gig ram
1TB harddrive

I'm not aware that X2 processors are MP capable, Opterons are however. And you should rather go with an even number for you memory (2GB/4GB) to keep it running in dual-channel.

No they're not. You need Opterons, 265's at least. They are pricey, and the MoBo:s are pricey too. A single dual-core CPU is much more computing per $.

But if you feel rich and want 2xdualcore, get an NVIDIA nForce 2200 based mobo. I wanted to fit my system in a standard ATX case, so I ended up with the Arima NV300. Warning: Do not buy the MSI dual opteron Mobo:s, they have nonstandard heatsinks and all sorts stability problems. I tried three of them, they all went back to where they came from.

This is not the place to bring fanboyism, i run an intel chip myself as you can see but if Athlon64 and Opteron are better than Pentium4 and Xeon at the moment, i can admit and support that.

Hmmm..well I do most work on Athlon dualcores, so I guess I'll have to meditate a bit on the 'intel fanboy' label for a bit

I agree its not a factor in choosing one over the other, but, its a simple fact that amd's generate more heat, and you have to be a bit more careful (during heavy usage) for cooling...especially if you wanna purchase a, let's say, x2 3800, and do the nasty, overclock...

[Maxer]

aitraaz, I still don't understand your obsession with heat on an AMD chip. Like I said I've got 7 AMD machines that stay on 24/7 and I've never seen any indication that heating up is a problem.

Your talking about overclocking a chip which is not something that 99% of the buying public are going to do with their chips. If you do choose to do this of course your going to have heat problems, you would have the same problems with an Intel chip, but don't confuse overclocking a processor with the normal operation of that chip.

Let's just say for the sake of argument that AMD's are running hotter than Intel’s by 10 degrees or so, why is this a bad thing? They are running hotter because there doing more work, and if your system was put together correctly you will have plenty of cooling fans to take care of your chips.

[aitraaz]

Ok, I guess I'll be off to me shrink tomorrow to get over this bloody heat obsession...

Agree on your overclocking observation...agree that if correctly cooled (which is most often the case) its a very slight probability that problems will arise...

The minor observation which I was attempting to make, which is most likely completely irrelevant, was that, at near peak level, the procs start to dissipate alot of heat...If an athlon runs at a higher level, it dissipates more heat...if you remove the heatsink from an athlon chip (sounds totally ridiculous and it is but veeery infrequently a heatsink can be improperly fixed or get damaged), it will melt down, and your box is toasted. If remove the heatsink from an intel chip, the system will hang, but you can reboot the system, the proc survives...

It's total silliness, (and i repeat ain't never been an intel fanboy) but thermal management is an issue which amd acknowledges they need to improve...

[Mihai]

aitraaz, that AMD run hotter than Intels is old news......have you compared the power consumption of Intels latest fiascos to the X2's or Opterons? The P4 and Xeons run hotter than the X2's, 64's or Opterons. Besides mb monitor the temps and shut down your machine if your fan should suddenly fall off

I wonder how long this AMD heat reputation is going to last.......

If that is the case, would a single Opteron be better than two Dual-core 4800+ chips?

The biggest diffference between the Opteron line of chips and the X2 line is the ability to work in SMP, meaning dual processors, or with the 8xx series of Opterons dual and also quad (2xx series Opterons only support up to 2 processors on one mb).

So if you look at clockspeed, equally clocked Opterons and X2s will have about the same performance. So get a 3800 and overclock it to the speed of a X2 4800, incredible performance for the money.

deja-vu i saw that post coming while i was writing...

never look a fanboy in the mouth i guess


But yes, you're right about the new dualcore intel's, they're hotter than hell -

One of the reasons on the delayed paxville-amd benchmark by intel was:

"They couldn't get a permit from the fire department to emit that much heat"

Just for the record:

Pentium EE under full load: 296W

Anyhows i wouldn't write intel off as total crap just yet...

Why wouldn't some Maxwell Beta (some using intel and others using amd) users just agree on a benchmark scene, a version of maxwell & then crack a batch of timed renders. Then compute a "rendered unit per hundreds of megahertz" for instance ?
This would actually be much more meaningful than urban legends about unverified claims on AMD chip thermal design power or supposedly inferior designs of intel chips (to restore some balance )
I just thought the original topic was interesting enough to recall it

hello

Code: Select all

Two Dual-core AMD 3800+X processors  
3 Gig ram 
1TB harddrive

Two AMD64 3800+ X² ==> nice choice... should be a tyanMB, isn't it?

3gig ram, ok ... think about having a OS wich could handle it (win2000 serv / win2003 / linux)

1TB harddrive??!!! man, we are talking about your working machine, not your data center ?!!

my system :

1 XP 1600+ & 512mo ddr running linux as dataserver & webserver : 2x200Go raid1 (dont wait for loosing your work in a HD failure before switching raid1, or 5) + 1Gb lan connection (very important)

4 work station (or render node) monocpu from amd XP 3000+ to AMD64 3200+ with both a least 1go ddr & 1Gb connection & 2x80go HD raid0 working both windows XP or gentoo linux

1 multipurpose server 2x AMD MP 2000+, 1go ram, 400go of unsecure harddrive (not raid) for texture & co, which ones are burned if the harddrive fail

working on a dataserver will help you working as team (if u need), will secure your files (raid), and the Gb LAN makes the network harddrive as fast as the local ones... even faster if you use RAID 5, or 0 + 1

i think AMD are good for the workstation, & intel for the render node ==> new P4 840 dual core have a better price/power than AMD X²...

best regards

aitraaz, how come you're so quick with the "fanboy" comments, I and every hardware reviewer and benchmark out there tell you AMD's are better at rendering, so I guess that makes you the fanboy

I guess so!!

I have X2 3800+ and I overclocked it. now i`m getting speeds over 4400+
Nothing to complain about at all.

I found this review awhile ago while I was looking into which is the better dual-cores. I hope it helps.

Really? How did you do that? What type of cooling support are you running?

X2 3800+ is a good choice!
