New Computer Build Processor and GPU

get the xeons
my mac pro with xeons? i'll let that thing render for 7 days straight and i don't even sweat it..
my iMac or MBP with i7? it gets scary after 30 minutes or so.. fans ablaze etc.obviously there are other factors here (fans etc) but still, i just have way more confidence letting xeons run a max capacity for long periods of time.
i guess it could all be in my head though and not real
-
There is really no difference between letting run xeons and i7s.
The factor here is in what they're embedded.
iMac or MBP => Case as thin as possible. No surprise there is little air flow. CPUs goes to high temperatures.
Mac Pro => Bigger case, so more air flow, lower temperatures.But even the Mac Pro is not the ideal case. For that I'd go with a Fractal R5 or something like that. (Bonus point, it would be a PC!)

Definitely not going to be a MAC, we only use PC's. I can use a full or Mid tower if necessary.

wasn't suggesting that.
the processors are the same though -
You'll be happier if you get a full tower. I would also suggest going with liquid cooling. Myself I get sli boards and then plan to expand video cards at a later point when the price dips.

personally I wouldn't go with either one, I would get an AMD. Their benchmarks are pretty much the same, but the price point is ridiculously lower than any comparable intel chip.

I was under the impression that the AMD Processors weren't even close to the Intel as far as performance? I'm building this computer to be fast and strictly for rendering, and was considering the Dual Xeon E-5 2640 8-core, or similar. Does AMD have something comparable? And is AMD reliable??

he has $7g though.
you're supposed to spend his money, not save it

They're not...

@ Devin - I have both. Some not that new AMD (6 and 8 core) and a newer Xeon Dual core. I'm planning soon to upgrade my AMD mobo and CPU to Intel, since, as Krisidious points out, a high-end i7 will completely wipe out any AMD chip. Hell, my i5 laptop almost matches my 6 core AMD...
Also, since this is a hardware thread, I'd be glad to see what advice people have on CPU coolers. So many choices!
-
I use a simple Corsair Hydro closed system. However, my system never takes the kind of abuse a render machine does. I just model houses...
For video cards I use Danger Den and a custom built system.

excuse me while I clean this mess up....

Regardless of pure performance, he stated that he wants to use this machine with Vray. And in a few months you should be releasing v3, right? Which means Embree, right? Which means Intel, right?
Right?
-
Thanks for all the responses. So Intel is in AMD is out! Any thoughts on GPU configurations? We all currently run the GTX 780ti, my initial thought was to pop three of them in to start (we also use Lumion and Octane on occasion)...

Yeah, hard to wrap my head around having that budget for just one machine I guess. I can't say how our product performs in a production environment for any particular configuration. I use a macbook pro that's a year or two old, and a desktop I built (amd based) for DR or RT rendering. I don't get too fancy when rendering for my own testing purposes. If I had 7k, I'd build a little 3-4 computer render farm. I haven't tested it myself, but I would think that having 3 or 4 machines contributing to the render job would be better than paying 4-5x to get 2x performance boost. It also depends on what you're rendering. If you're doing more quick renders than big slow renders, then the network lag on DR would probably have an impact on performance when dealing with the farm. Otherwise I would think that having the farm would be the way to go.
One AMD FX-9590 Eight-Core (score 10,194) is $219.95
One Intel Core i7-5960X (score 16,905) is $1,011.99... so there's some improvement here, it's nearly 7,000 higher in the benchmark score (not sure how that relates to V-Ray though)... but you have to pay about 500% for that little bump...I'm also confused why intel server chips (xeon) are listed... but no AMD (opteron)... not sure why they would be omitted...
So for a benchmark that is actually related to what we do, here are benchmarks for 3D Studio Max using Mental Ray: http://www.tomshardware.com/charts/cpu-charts-2013/-26-3DS-Max-2012,3161.html
Again I'm seeing under $200 for AMD, and over $350 for intel, with similar benchmark scores.
Granted, you have a huge budget, and you already have a render farm, so by all means, go on and get the absolute latest and greatest processor you can find (or a few of them for that matter). Like I said, I just have never had that kind of budget for one workstation.

space and power get to be a consideration once you have many boxes... also noise, heat. Additionally, you have to consider that node licensing has changed with vray 3.0 - you have to pay for nodes now, so it make sense in that regard to have fewer machines (thinking ahead at least
). @ Devin: I don't know if you realize that AMD cores =/= Intel cores. Intel uses hyperthreading, so you pretty much get double the cores in terms of processing power. I.e. - 4 cores Intel = 8 cores AMD, more or less. -

I don't know any benchmark info at all for our product unfortunately, and I can't say exactly what V-Ray for SketchUp 3.0 will or will not have at this point, or how it will benchmark on a given configuration, it's still kind of early in the dev cycle.
AFAIK any high end cpu (intel or amd) that supports SSSE3, SSSE4, SSSE4.2, or AVX... which should be able to use Embree.

I.e. - 4 cores Intel = 8 cores AMD, more or less.Yeah, I'm aware that amd cores != intel cores. I believe that we charge per every 10 render nodes if I recall correctly, so yes, there is an additional cost (which could be covered by not purchasing a $3,000 cpu). Like I said, I haven't really done any benchmarks, and my job doesn't really involve rendering a ton, I just write the plugin, and talk to you nice folks
Heat, noise, power consumption, etc. I remember back before we had our in house render farm enclosed in a proper server room... Granted, we had a farm of 30+ rack mounted nodes, and not just a couple machines sitting around, but it can still be an issue with a handful I guess. I think one of our developers here has 5 computers at his desk alone, 6 when he brings in his laptop, 7 when he brings in his other one, so I don't think of <10 machines as a big issue.
