What hardware are you using?

I've been working my way through the beginner's learning flow and have been enjoying the exercises.  The trouble is, my IT set up has not.

I'm running a Dell XPS-15 laptop with an NVIDIA GT 750M graphics card and it's pretty slow when rendering single frames - I've not got onto animations yet!  Watching tutorials, others seem able to move around and edit scenes in viewport render mode with their systems responding quickly but I can't do that.

So I was wondering what equipment other people are using and how it performs for them.  What I'd like to understand is the optimum mid-range set up which will cope with short animations and photorealistic scenes without becoming obsolete before it reaches the end!

(Just for info, I have set up Blender to streamline renders to the maximum extent (tiles sizes, restricted samples and light bounces etc) and I used GPU compute until I started getting CUDA errors but, to be honest, there didn't seem to be much difference between GPU and CPU.)

Anyway, I'd be interested in hearing other people's experiences.

Thanks in anticipation.

  • If you're going to get into Blender, get a desktop computer. Server class, dual CPU, and try an AMD RX Vega GPU if you can dish the dough. If you can't, than get a Nvidia Geforce 900 series. You'll need a decent amount of VRAM if you want to use Cuda or OpenCL, I'd say 4GB at least. Don't forget that you can also use 2 GPU's to get twice the GPU render speed. However, that doesn't mean you'll get twice the VRAM, just twice the processing power. That means that you can get a mid-tier GPU, hook them together, and get more power than a high class. At one point I had 2 GTX 970's and I benchmarked higher than a Titan. I can't recommend a good CPU, as I don't know much other than Intel's i9 and Xeon. Remember that Google is your friend.

    I'm using a first generation Core i7, 16GB RAM, nVidia GTX 750 Ti with (I believe) 4GB

    I've never gotten CUDA errors but maybe we are just working on very different things. I can certainly use the viewport in render mode without much trouble using the default sample size. 

    One thing that used to always trip me up was that I had set up GPU compute in the user preferences but I would always forget to set it here:

    so then I'd be cursing at it "why are you so slow!" then I'd realize I didn't have GPU on for that scene.

    For what its worth the 2.8 pre-alpha-preview supports using both GPU and CPU at the same time which seems to speed things up slightly, though CPU rendering always make my fan go to such high RPM I'm afraid it will wake the neighbors!

    I personally notice a HUGE difference in CPU and GPU rendering times. If you want you can send me a file and I'll let you know how long it took on my hardware so that you can compare.

  • Cool topic, since two weeks ago I got myself some new parts :)

    My computer specs are:

    Ryzen 1700 3 GHz, 8 core, 16 threads

    16 GB RAM,

    GTX 1070,

    This should be ok for a long long time :)

    I use an MSI GE72 2QF Apache Pro laptop (12gb RAM, GTX970M GPU, and i7-5700HQ CPU). It's not top of the line, but it renders fairly quickly as long as I stay on top of the render settings.

    I know what you mean about slow render times, though. When I first started with Blender, I had a GTX570 Ti and it was so slow, I didn't switch to Cycles until I could upgrade to a GTX780 (a used one).

    Oddly, my laptop outperforms the desktop I had the GTX-780 in (other specs: i7 2600k, 16gb RAM). Not by much, just a few seconds per frame, but it was enough to illustrate Moore's Law.

    AMD - Threadripper 1950X      16x32
    G-Skill Trident RBG something DDR4 32GB
    Gigabyte Aorus Gaming 7 mb seems great!
    AMD Vega FE wc (x2 currently only using one - might set up a render box with old PC)
    Not nearly as many driver issues as when I first got it ... lol ... should get better still, I hope.
