GPU Configuration for workstation

Hi hello!
I have a question. I need it to render small interiors, e.g. shop insides (with lights, metal constructions, a lot of polygons). One scene is aproximately 1800 frames and use 9 GB VRAM without out of core). I must to render it in less than 30 hours. What configuration do you use in similar projects? How many GPU's may I use in a work station? I would appreciate your suggestions :)

It sounds like you're looking to reach 1min per frame which for my system is tight on all but the simplest scenes (but I don't use noise reduction). Looks like you'll be looking at top tier cards depending on when you need to purchase. Right now you can't buy 3080/3090 cards and 2080ti blower cards are rare on ebay...

I run 2x 2080ti and could render the scene for you to get a baseline if you'd like, but I imagine you'll need to set a time limit, activate adaptive sampling with a noise threshold around .7 and use the denoiser unless you get more than one render machine.

I believe 8 gpu is the limit to a single workstation but for most people they can fit 2-4 gpu on a standard motherboard with standard cooling. If you go with 4 3080/3090 the power draw becomes a concern which is unfortunate.

We get 30sec to 2 min in AO with 24 GPUS (mostly 2080TI)

What’s AO in this context? An octane bench scene?

Also what’s the standard setup for a single designer / home studio setup? I can’t imagine dealing with more than 6 high end gpu in my 100+ year old apartment electric/ cooling and space wise.

Hi,
for 1800 frames I would have a look to ORC or RNDR to get the power you need ;)
