Dual Xeon or Dual Opteron ??? (Moved to Community Forum)

Hello everyone,

I just wondering which system is the best for zbrush. After reading some Faq it’s clear that multi cpu system is better and that the amount of memory is important. I know that opteron system is super fast when it’s about memory benchmark. In the other hand pure 3d software rendering seems to be faster on xeon’s, so I really don’t what to do :). We are planning to build 3 or 4 systems meanly for zbrush and other 3d softwares and the purpose is hires game character creation (with normal maps)

tks for your help.

I realy have no Idea , I have never benchmarked Zbrush on such systems…

Opteron, it is possible to have more memory overall…

Xeon is made just for dual processors, they play well together by design…

Opteron has Hyper transoprt…

Xeon has only 32 bit capabilitys…

opteron has 64 bit, and 32 bit capabilitys…, suposidly they have NO bottleneck useing the DDR ram

Personaly I am getting the dual opteron system…

Perhaps someone in the comunity has both and can do a benchmark test for us

thks Polaris30 for your reply.

you’re right, you can put more memory in a opteron system, but the actual version of zbrush is limited to 4gigs anyway.

Moreover I’m really not sure if you can render 4gigs of polygons in realtime with an actual dual xeon/opteron system.

I don’t know how the inside zbrush benchmark is revelant. I guess it gives a good idea, but I would prefer an overall advice in an everyday work, like how many polys you can render and work on.

doesn’t matter if you get a terrabyte of ram, windows limits the size of the process space for programs to 4GB, so I think this would be a limiting factor to memory usage.

well here are a couple of more pieces of worthless trivia, to help pass the time 'till the smart guy gets here…

Xenon systems you can purchase chips with higher MHZ …

AMD claims that MHZ dose not always equal speed… they claim that they don’t take up any system ram to speak of, and that there is no bottle neck like on intel systems when dealing with DDR ram …( I am really not sure if they where saying in 32bit,64bit, or both modes) so if this is the case possibly Opteron is superior as to how much of your 4GB can you actually use…you might “Get more bang for your buck” from Opteron as far as your system ram is concerned…

This is why I would like to see a benchmark type of test done with a dual Xenon and a dual Opteron with same MHZ,and 4GB maxed out ram, to see who comes out first…

Thanks for bringing this topic up… I am really interested in the same knowledge you seek.
