Hello,

I was wondering if i could get some opinions on a new system i'm thinking of building.

here are the pieces that i would like to put in for my base system:

Enermax FS-710 B-1 ATX Tower Case
Enermax Whisper EG-465P-VE 460watt
Gigabyte GA-7DPXDW-P AMD760 RAID ECC DDR MOBO
2 x AMD Athlon MP 2800+ .13 Micron 266 FSB
>>>>WHat kind of performance gain will i get if I get the 2800 barton core chip?<<<
2 x DDR (266) 2100 REG ECC LP - 512 MB Kingston RAM

All opinions are very much appreciated. thanks.

Performance gain compared to what? your current system? or if you would use two lower-rated Athlon MPs?
What do you want to use it for?

performance gain between the non barton 2800 and the barton 2800.

trying to build a dual cpu system for graphics work - i have a dual mp 2000 at my work which i'm very happy with. want to replicate (and make something better) the system at home.

any opinions on the gigabyte dual MP board? should i wait for the next wave of opteron releases and go opeteron? i want maximum speed and maximum RAM for about 1,000 (barebones system - I've got the ohter guts already)

thanks.

There is no T-Bred Athlon MP 2800+, the fastest non-barton Athlon MP is a 2600+(there is also a barton-version of this, IIRC).

Just so you know, an Opteron 240 costs about as much as a Athlon MP 2800+.
The MSI K8T Master2-FAR is about the cheapest dual Opteron mobo i could find(around 216$, newegg.com) - it has an AGP-slot but uses a 4+0 memory architecture, which means the second CPU will have to share memory via HT with the first one.

I don't really know if a dual Opteron 240 or dual Athlon MP 2800+ system would perform better for your specific applications, but the Opteron-platform is certainly more future-proof. If the 240's aren't fast enough, you could always upgrade to a faster model when you can/want to afford it.

Prices(from newegg.com):
2x Opteron 240(retail) - 432$(216 each)
MSI K8T Master2-FAR - 216$
2x 512MB Corsair PC2700 ECC Reg. - 270$(135 each, from Monarchcomputer.com)

Stay away from the enermax 465. I had one and had nothing by system problems due to pair amp. I upgraded to the 550 server model and had 0 problems since

Hi,

What apps are you intending to run on this monster?

I ask because everything I find out suggests that the Opteron solution is great for apps which have a high memory bandwidth requirement.

But for apps which require raw CPU power (as opposed to CPU+Cache+RAM combo power) the Athlon MPs offer almost as good a solution at a much lower price.

If that's right, it's interesting because it means that a MP2800 will actually be 15% or so faster than the MP2400 for those apps where you should be looking at the MP rather than Opteron. The 2400 is relevant, because 2400 was the sweet spot in the price performance curve last time I looked.

But this arguement cuts the other way as well. If your apps are the high bandwidth type but you are not interested in an Opty solution, you may find that a single CPU (because it has higher memory bandwidth as well as not having to share it) might even outperform a dual.

Horses for courses...

I'm also looking for an optimal MP solution to render animation frames using Alias Wavefront StudioTools10. I plan on using 2 GB memory. I need speed but would like to get it for a reasonable price.

I am considering AMD Athlon MP 2400 2.0GHz @ $123 from NewEgg and whatever is the best (most stable) mobo. Any mobo recommendations? Any reason to upgrade the processors (other than speed)?

In that case you need to find out the resource demands of Alias Wavefront StudioTools10.

Serioulsy:

1. Is it multi threading? - if not you will get zero benefit from the second CPU.

2. Is it memory bandwidth limited? If it is, the second CPU may not give you more than a 25% performance boost.

3. But if its raw CPU Mhz hungry and multi threaded the MP is just the baby.


The vendor site should tell you whether it is mult threaded, and if it is what sort of performance improvement you get from the second CPU.

If it isn't mult-threaded and you are looking for a cheap solution start with an overclocked XP2500.

If it is multi-threaded but the performance boost is low, also consider the overclocked Barton. The low performance boost means the Memory is an important factor, like I said. In that case the XP overclocked to an XP3200 and with its higher memory bandwidth may give you similar performance to two MP2800s, but at a lower price.

Of course, in that case the technically ideal solution would be a dual Opteron - 2 powerfull CPUs plus high memory bandwidth. But pricy.

I think if you can swing a Barton based MP you would be better off than tbred core.

On an MP's system both CPU's are always fighting over memory access, the extra cache in the barton should pay off quite well on intenive SMP applications as it should lessen the memory load.
