Hello all of you,
Im getting more and more jobs in CG and im looking into building a seperate cycles rendermachine but one that can also do some scenes in red shift or octane.
Im doubting allot what to do. I have several options. I already have a good workstation 5900x with 3090 and 128gigs or ram. The issue is that rendering stills takes allot of time sometimes and the turnaround is fast. Also i cant render and work on scenes at the same time.
So i cant and dont want to pay for all of the stuff new but these are my options and i just dont know what is the best idea.
1 put another 3090 in my system everything faster but still the issue of not being able to work while rendering
2 buy a decent second hand treathripper system with 128 pcie lanes and a board with a minimum of 4 16x pci slots. And then start putting more cards in there.
3 same as option two but then with a board with up to 7 pci slots and keep putting more cards in over time.
The issues and doubts i have are the following
- how do you manage power if you have 3 or more 3090s for example.
- does cycles x even work with like 4 gpus
- how to send the renders to this render node (ideally its not in my home but in mijn studio (way cheaper power)
- can you mix different nvidea gpus for example a 3090 and a 3080 and a 2080ti or any other card? Does it al work together or not. And is your renders memory usage bound by the lowest memory gpu?
-sometimes i see boards with like 7pci slots which seem great but then the are two slot thick apart so that will never work. Can you use like miner extenders for that issue to still connect that many cards.
All of these things and more make me almost not want to do it. Also letting a render farm do the work is not an option for me. I see those prices and within a couple jobs you have a extra gpu saved up. Also i like to make multiple render versions and i dont want to pay everytime.
So i can buy a decent threadripper for like 2000 euro or less depending on the model. Cheaper ones have pci 3.0 not 4.0 but i dont know how much thats a issue.
i looked for a answer on the forum but the topic i found was 10 years old.
