suggestion for faster rendering

[Santander]

Hi guys,

the pc i work on consists of a GTX 1080 8gb and 2x8GB DDR4 Ram and i7-6700 and samsung 850 evo 250gb SSD.

 

As i am using 3DS max, after effects, corona, vray, lumion, twin motion.

But when rendering a 4K content (eg. convention centre)  to its whole length it takes about 2 days+ and i also get severe lag sometimes.

 

So what can be done to speed up this process. what does rendering is most based on CPU cores or RAM or Graphics.

RAM and CPU cores would be your best bet.

What render are you using?

 

Its probably cpu limited.

 

Id suggest that you rent render farm if you want to render fast and have some cash.

 

If you don't, get somethign like a 6 core i7, or a  faster system.

 

If you want a render server, get something like a dell r710 with dual 6 cores(about 400), or a r720 with dual 8 or 12 cores if you got 1-2 thousand to spend.

 

If you don't wnat the system to lag, you can lower its priority, or limit the cores it can use.

Perhaps you can enable GPU rendering?

 

Or you can upgrade your CPU to something with more cores, which may be expensive.

You might wanna either upgrade to a xeon or a core i7 6800k or 6850k

More computers.  Rendering computer graphics from software like Blender, Maya, 3DS Studio Max, or Cinema4D are highly precise and demanding rendering systems.  Suggestions to upgrade your workstation will only get you so far, frankly, between an i7 6700K and just about any single CPU you can put into a workstation, you will have to get up to 10 core Xeons and above chips before you can even double your output.  The real answer is more computers.  ...Or patience.

 

Signed, someone who did three hours of overtime today, watching the farm at work chew on a Nuke script and while each render node could individually only manage 40mins/frame.

its my brothers computer..he always comes and ask me to find a solution to it...and also i am new to this rendering stuff... i dunno much about the inner terms..all i know he uses this pc.

 

and lets say if i change the cpu to 6800k  and upgradethe ram by 4x8gb ..will that have a notable difference and can you say by how much.

Probably about 40% faster assuming cpu rendering.

 

The ram won't make it any faster. You either have enough ram or you don't. I

Going by the CPU Mark scores, you would get about 23% more throughput.  ...And you'd be about $380 USD poorer for the CPU. ...And then there's the cost of the motherboard...

 

See  my point?  Just upgrading the box won't get you that far but it'll cost you a fair bit.

yea...unless it becomes a waste of money...so if we use xeon should i have to use quadro as it have ECC or will 1080 do just fine..?

Quadros and Firepros can have advantages in some software that would make use of GPU acceleration but that doesn't mean that your software or render engine within the software can use them.  The use of GPU acceleration is really job specific, so I wouldn't worry about the GPU until you're specifically running something that can make use of it.  Computer animation is not like gaming, they aren't inherently hardware accelerated for a few reasons.

no no the 1080 is fine

[NTDaws]

the bottleneck is the CPU

all he uses is the above mentioned softwares.

can someone suggest a CPU and RAM and any other hardware for this setup 

[Santander]

so why no one is using AMD FX CPUs as it generally have more cores than intel....and also why no one is suggesting firepro over quadro.

I cannot comment on the AMD, as I can't remember the last time I had an AMD CPU - actually I think I had a 3dfx AGP graphics card. That's dating myself.

 

As for the GPU, I wouldn't recommend a firepro or quadro. I built a render machine for someone with 780Tis in SLI and it outperformed a quadro that cost twice as much. The lower end GPUs are not listed as officially recommended by Autodesk. I did however find that iray rendering improved if the GPUs were not in SLI. This was mostly in 3ds max, but some lumion 3d work as well.
