i7 6900k vs Duel Xeon 2670 v0

[apostolischristou]

I am working on 3ds max and and i am currently building a new workstation . Rendering in corona(cpu renderer) .

 

Well in the office we already have a single-Xeon ES 2690 v3 and we are not satisfied at all, material editor is slow as hell and everytjong runs alow Expect render times which are good. According to benchmarks render times between i7 6900 and dual xeon 2670 are not even close(2670 wins easily) . Here comes the "But" : If i can design better and handle bigger scenes like 15m polygons+ (which i cant do with the 2690) I will win the render times in those things and also I xouls jump on gpu renderers later on.

 

The rest bulding will be:

Mobo:asus strix x99(i7) or the asus for the duel xeons.

Ram:4x8 corsair 2400 ghz

Gpu:1070 asus turbo(since we wanna build a fpu station later too)

Psu:corsair 850cs

Cooling: corsair h110i v2

Ssd:samsung 850 pro evo 256 gb

 

 

Thanks for the help anyway

For modelling you want a cpu that has a high single core speed:

For rendering you want a cpu that has a lot of cores/threads:

An overclocked i7 6900K will get you high single core performance and solid rendering times. Up to you too choose. You could build a modelling pc and have a seperate pc for rendering.

Hi Apostolis, and Χρόνια πολλά!

 

How much are you going to spend on this new rig?

 

Dual v1 Xeon systems will be slower in modeling and editing processes due to lower single core performance and older architecture (lower ipc), as Joel already mentioned. But don't be mislead about their rendering performance. A 6900K or a 5960X oc'ed at a frequency of around 4.3-4.4GHz would be fairly close in rendering times, not more than 10-15% slower compared to the dual 2670 v1 system. Their single core performance though would be way better (~20-30%).

 

And there is another option too (Joel mentioned it). You can build a 6700K based system for modeling etc. and keep the 2690 v3 system as a node for rendering, or (if the budget is enough) build a new one from scratch, based on used 2670's (v1 or v2, you can find them for under 100€ a piece on ebay) and a used Z9 motherboard. The 6700K would be the fastest cpu for modeling/editing right now (especially if oc'ed) and I'm sure it would help you decrease your non-rendering working times by a great deal.

I really like your 3d idea and I think its the best solution.

 

90% will go with 5920k overclock machines for our main pc's and buy an extra refurbished 2x2670 v2 render node. Thank you καλή χρονιά να έχουμε

Since you won't be needing multiple gpus and the renderings are going to be left for the render nodes, I think that there's no meaning in building your main workstations around the 5930K. Either go for a Z270/7700K combo, or, if you definitely want to invest in the s2011 v3/v4 platform, pick the cheaper 5820k/6800k. You'll be fine with them too. The 5930K just offers 12 more pcie lanes, which won't be of any importance in your case, since you'll be using a single gpu in each WS.

I am going for 5820k ( 5920 was a misstype ) I will buy 1x1070 for start but will buy more GPU's later this year for about 3x1070 cuz i will be using some gpu renderer for some products(adjust them to the modeling machine not the render node).You think a combo with 5820k+x99 strix gaming 11-13 mobo will be good for that?

[Nikolaos M]

For up to three gpus in total you'll be fine with the 5820k or the 6800k, which is the newer 6-core i7 of this class. x8 pcie 3.0 lanes per cpu should be just fine for gpu realtime rendering.

 

In your place I would go for a 4-way sli capable motherboard in order to have plenty of space and correctly/evenly spaced slots to install dual-slot gpus. A good motherboard for this job, which won't cost a fortune either, is this one

I would combine it with an i7 6800K http://www.skroutz.gr/s/9141628/Intel-Core-i7-6800K-Box.html.

 

One more thing. For 3x1070 and gpu rendering I would pick a psu on the safe side, ex. a good quality 1000W psu. Here are some good choices:

http://www.skroutz.gr/s/7593572/Corsair-RMx-Series-1000W.html (10 years warranty)

http://www.skroutz.gr/s/10777283/EVGA-SuperNOVA-1000-G3.html (10 years warranty)

or if you want platinum efficiency, this one http://www.skroutz.gr/s/4344534/EVGA-SuperNOVA-1000-P2.html (10 years also).
