@@fatcatpeople keep the brands separate for best results. And keep your eyes on the supported GPU lists for the program you want to render with. AMD driver and GPU support is not as good as Nvidia. So make sure you read into it. For Blender 3.3+, Nvidia from Kepler architecture up to current, and AMD, Vega 56 and similar, and 5000 series and up are supported. 500 series and older are not. So be careful with buying GPUs
I have actually never tried that! As in, just plug it right into the USB ports on the motherboard? I will try that soon. Good idea. That would save a ton of headache with risers
@@ContradictionDesign I know, I'm also thinking about getting a PCIE 4x16 with USB-C slots that gets upt to 20gb transfer rate shared to 4 slots. That way i can just buy USB 3.1 to USB-C cable... Man EGPU cases are expensive and these used mining rigs are all over the place way cheaper. Been searching a 4 slot M.2 NGFF adapter in ebay non has them . thanx
Mostly I want to make the rigs more dense. Every setup has idle power use and needs to be controlled separately. So fewer big rigs is better than many small ones.
that tiny x1 to usb 3.0 expansion card are very low in bandwidth, there is pcie bifurcation multiplier card that uses x4 pin instead, this is the best i could find available to buy much better than those x1 pin that are fine for crypto mining purpose but not for heavy compute work, i wonder why they don't make x8 or x16 though surely there is demand, 4 usb 3.0 ports on x16 lanes pin expansion card would be superb, 4 pcie lanes for each gpu. i wish.
Yeah an 8x would be nice. I have tested the 1x risers and they create minor performance bottlenecks, but mostly in scenes where loading time is a significant amount of the render time. For complex frames, the loading is relatively short so the performance hit is basically nothing. I know they make plenty of 16x risers, but they are expensive and bulky.
Awesome Job, just a question, instead of pluging the pcie adapter to the mother board, u think getting a 4 usb 3.1 adapter thru pcie 4x16 will work, trying to make 3 gpu's on riser and one in the pc or mac , the 3 on risers are slaves. will that be a comlicated project? thanks!!
As long as the adapter will allow your OS to see the GPUs normally, it should work. You are trying to get more lanes for each GPU I assume? Like 4 instead of 1? Either way it should work. Just know that once you get too many devices connected, it will confuse your OS. So don't plan on using 6 of those adapters or anything crazy. Might get away with 8 GPUs on a machine. Maybe more. I am kinda testing these ideas myself. Long reply sorry. But just super exciting stuff to me!
@@ContradictionDesign Naahh.. I have a Mac Pro 5.1, will use only 4, 3 slaves and Master in the system. also will be running Linux and Bootcamp Windows 10. I found a usb 3.1 Pcie 4x16 slots that has 20gb Transfer Speed...Hope they work, thank you bro!!!!
What a great video. It explained clearly what I needed to know
Thanks, and I'm glad it was helpful!
Let me know what to test next. I am planning a video about safety with powering computers already. Thanks for watching!
Do all the GPU's have to be the same for a rendering farm.

@@ContradictionDesign ill just got with nvidia to keep it simple. 👍🏽✌🏾
Thanks for this benchmark, I bought a bunch of CMP 50hx mining cards, but I know they work in blender so im going to try this maybe :)
Oooh I have wanted to see if they are good for Blender. Let me know if you try it. I have been eyeing those GPUs as well
Thank you Bro.
You are welcome!
Have u tried to use just the USB 3.0 without the single pcie adapter?
I have actually never tried that! As in, just plug it right into the USB ports on the motherboard? I will try that soon. Good idea. That would save a ton of headache with risers

@@vergelbansill9811 I have tried PCie to USB splitters but they are hit or miss. It really depends on what the motherboard will recognize
@@ContradictionDesignNo! It does not use USB protocol so it will not work. It just uses a usb cable for it’s pcie communication.
so you are trying to see if you make a larger farm??
