what multiple cpu is better for 3d rendering

[Calin Cristian]

hello all.
It is the first time in my life when I ask a question on forums.
I need a multy cpu configuration for 3d rendering. I have in mind 2 xIntel® Xeon® Processor X7560 8 core - 16 tr but some people think that a single latest i7 model will be better. i can invest round 2 000 euro in cpu and motherboard. i was thinking of Z9PE-D8 WS as mothrboard. I wait for your help. Thank you.

thank you very much for the detail explication, Bambiboom. I already have the nvidia quadro k 5000 mac and pc versions.
I decide also to sale my old mac pro so I can add 1500 extra to what i shave now, so I can spend 3500 euro for the cpu motherbaord and Ram.
So according to what you say I can not find motherboard for dual cpu slot that accept ECC ram for 1866 ?

I had a scene with 80 milion polygons and render it with mental ray and 12 lights with shadows in the scene. was amazing to compare the render time with a laptop XMG with 2 x nvidia 3GB(can t remember the model exact) and my system with the k 5000. was only 40 sec difference 🙁

In other comments from my facebook they say that maya will use as much as threds and cores are found in the CPU and now i found out that it s more important that I must have more clock speed.
So at the end it s good that I get 1500 euro extra for the new config.
I also look for ECC ram for 1866 but I didnt find out there.

Calin Cristian,

Yes, Maya is a difficult application to maintain in good performance and in fact rendering / animation in general is the most demanding. Every component > CPU, motherboard, RAM, GPU, disk,and system cooling has to run for very long periods at the highest performance. Fortunately, applications are finally taking more advantage of multiple cores and Maya and Adobe Premiere are just in time. I am working currently on a Sketchup model and while the file is only 52MB, the nearer I am to finishing, the nearer the file is to being impossible to use. > I have to put everything on many layers and turn off everything except the tiny portion I'm working on at the time. And, this is in consideration of the Xeon E5-1620 is running the first two cores at 3.8GHz. For this reason, having an increase in your budget is very good news, and if the Xeon E5-2687W V2 is possible, on the ASUS Z9PE-D8 WS motherboard, good RAM, and the excellent Quadro K5000, then you will be in the best possible position.

On the subject of RAM, the 1866 speed ECC is becoming more accessible almost daily and looking forward, as the highest native speed ECC, it is advisable in a system on the level you are considering. Here is the Kingston 1 X 16GB module>

> Not giving it away, but only about $15 US more than 1600. I didn't check this however with the ASUS list of tested / approved RAM, but ECC 1866 does seem to be more available.

Something I meant to mention is that Intel advises users of the 150W E5-2687W to use liquid cooling and I think something like a Corsair H80 os similar would be sufficient. This is important of course as that - and later those- very expensive CPU may run at top click for hours or days. Also, for this system, have a large (plenty of drive expansion, easy to get in and work on it), airy (cooling) case like a full tower, Luan Li, Corsair 900D, or my choice which would be a CaseLabs because they may be so carefully optioned.

When you have chosen the components list for the whole system, you might like to post again in the Systems forum and there is certain to be a lot of suggestions of how you can spend more money.

Interesting project!

Cheers,
