Hi guys. Just created an account with a question I have. Seems like best place to ask it.
How it will -possibly- affect the performance of a card.
Planning to get TRX40 Designare for TB3 (but I can yet switch to one of these Asus’ triple x16 boards) I also want to slap two 1080Tis (waiting for 3xxx series for upgrade) I’m using now. Unfortunately second x16 slot on Designare will be by default assigned to that Quad NVMe card which is in the box (will use 8 NVMe drives, up from 6 on existing Zenith Extreme X399 system). My question is:
How using Gen 3.0 VGA in Gen 4.0 x8 slot may affect the performance. I don’t talk about gaming here. Interested only in rendering. Using CUDA/IRAY ecosystem (DAZ/Blender/MD/bits of Substance and Resolve).
I know that for gaming there is no issue, even ignoring the fact there is no support for SLI these days, all of my … few… games (like ME Trilogy) are old and never break 60 FPS so couldn’t care less about gaming.
Problem is that rendering is much different thing. When you load GPU, memory and frame buffer to full with tasks and textures suddenly that x8 electrically starts to have some impact. Read multiple articles and most of them direct me at the 80%-85% of nominal performance.
Sadly can’t test it in any way. Don’t have time or hardware to do that. All input much appreciated.
