GPU or CPU for 3d Modeling and rendering video

9_breaker · Oct 30, 2015

Ok I'm looking to build a PC only for 3D modelling and the adobe suite. I will not be doing any gaming at all. My question is what's more important for 3d modeling and rendering video between the CPU and the GPU?

Also if it is GPU, how much difference does it make? I can't seem to find any benchmarks apart from gaming ones. For example how much faster would a Titan render over a 970?

It depends on your budget

Well my budget for the build will be about US$1300 might be more depending on what I need.

9_breaker :

What 3D modelling software are you planning on using? Are we talking 'game modelling' (e.g. maya / 3D studio / Rhino), Mechanical Cad (e.g. Solidworks, Geomagic etc) or Architectural (Revit, Autocad...)?

Depending on the answer to that you may need to look into a professional workstation graphics card rather than a gaming card (e.g. AMD FirePro or nVidia Quadro- they cost a bit more than gaming cards but in their intended software they are way faster due to dedicated drivers).

Also when you say rendering, what software / type? Video rendering for example is usually gpu accelerated (in which case you need to check what acceleration features it supports as AMD and nVidia offer different options here). For 3D rendering from CAD, your usually looking at *cpu* rendering, in which case you need as many cores / threads as you can get and can use a less powerful gpu....

I'm planning on using 3ds max and by rendering I mean videos in after effects. I'm still relatively new to modelling so I'm not planning to go the workstation route.

Thanks for making me build. This looks just like a gaming build. Is that how it's supposed to be? Are Modelling builds pretty much the same thing?

It is somewhat of a gaming build... But there are reasons for the CPU and GPU picked

The i7 has 4 strong cores and 8 threads making it the perfect choice for multi threaded tasks

The AMD architecture of the 390x has higher COMPUTE performance, which is better for rendering...

But as the guy above me said, it depends what your ender and model, if its like architecture and things like that sticking to professional workstation cards are your best choice

I've had a look on Autodesk's website- they only recommenced workstation cards for 3Ds Max so I'd go that way- they aren't actually that expensive for the lower models and will perform better than a gaming card (trust me on this if the software is written with a workstation card in mind it will run like a dog on a gaming card unfortunately).

The AMD FirePro cards are all supported and are usually much better performance / $. I'd look for a FirePro W5100 as a nice mid range option that should be within your budget.

There are a few consumer cards supported like the 690. Which would be best between the FirePro W5100 and the 690?
