Quadro 4000 - Rendering slow in win7 64bit

[muhamedthufail]

Hi everyone ,

 

I've recently bought a new workstation pc to my office

Mobo - intel s2600coe

Processor - 1X Xeon 2620 @ 2.00Ghz

Ram - corsair 2x16GB = 32GB

GPU - Quadro 4000

 

Problem is that my pc is rendering much slower.

rendering time = 7m 56sec where as an old pc rendering time = 4m 25sec

 

I've tried changing driver to 3dsmax performance driver but no use .. is there somthing am doing wrong here ?

softwares used are 3ds Max 2013 , Vray 2.40 ...

 

Please help ... !!!!

Are you using the regular Vray or are you running Vray RT-GPU? If you're not in RT-GPU the Quadro card has no effect at all on rendering speed.

 

(Also, the Quadro 4000 is a few years old. If you are in Vray RT-GPU, and you're comparing a good current model Geforce card to a Quadro 4000, the Geforce will be faster.)

Regular Vray mostly .. it has no effect on rendering speed ? i just spend 50K for nothing ?

Vray RT is used as an 'active shade' in 3dsmax right ? what is the point of accelerating it if the hardware is not good with production ?

 

BTW ... i've read in some threads talking about 'enabling CUDA' mostly in MAC ... is there someway to do the same in Windows 7 ?

:(

Also .. I have a Geforce GTX 680 in my older PC and its twice faster than the one i have now ..

GTX is constantly crashing 3DsMAX when rendering walkthroughs thats the main reason why i chose Quadro 4000 over it ..

 

i've got a wierd feeling that buying a workstation was a dumb idea ... :/

As Andrew asnwered already, the GPU has nothing to do with rendering unless you are using VRay RT GPU (not just VRay, not just VRay RT, but RT with GPU enabled). Vray RT (GPU and CPU results through RT are the same) is not bad for production, it just lacks some features seasoned VRay users might require for their work. For some it is actually more than acceptable.

 

Which were the specs of your "older" PC?

Cause if you had a GTX 680 it was probably a 1-2 year old machine. Say a i7-2600K or equivalent.

 

The E5-2620 is a 6 core / 12 thread slow (2GHz) Xeon...roughly an aggregate of 12 threads * 2GHz each = 24 GHz of Sandybridge Architecture.

A 2600K is 4C/8T, but at 3.4GHz -> an agregate of 8 threads * 3.4GHz = 27.2GHz of Sandybridge Architecture.

 

In reality the 6-core could be slightly more effective per GHz in pure rendering, so give or take similar speeds in rendering, but much slower in single threaded applications. Your results are too different to make sense of (tho we still don't know what was you previous PC, other than that it had a GTX 680).

 

How did you know it was the GTX that was crashing your "old" PC? Were you getting a "nVidia driver stopped working" message or something equivalent before?

I would find it odd if a video card were the cause of a crash while rendering in regular Vray (a CPU only process). Could you tell us a bit more about that problem? Maybe we can resurrect that PC. You could use it as a render node and get a decent bump in render speed.

The 3D Max was crashing whenever i try to render a walkthrough .. i concluded dat its a compatibility issue because a lot of users had the issue as mine and all were suggesting updation of drivers and software which i 'did' .. and still it kept crashing

 

Thank you explaining in detail , now i understand

I was trying to save some cash by not buying the 2nd processor for the motherboard which seems like a wrong choice i made ..

[muhamedthufail]

Yes .. i will post the error message with picture tomorrow .

and yes am already trying the distributed rendering which works just fine ..

 

Thank you for the prior response .. i always get the solutions i want from the 'cgarchitect' ...
