GPU Rendering

[Wohnraumdesign]

System 1
CUDA CPU GPU Rendering have an AMD 5950 and an RTX 3080 Asus and a GTX 1080 TI Asus

System 2
CUDA CPU GPU Rendering have an AMD 3970 and an RTX 3080

System 1 is faster at rendering than system 2 although system 2 has 64 threads and system 1 has 32 threads and only one GTX 1080 TI more in the system.
Do the graphics cards really play such a big role in rendering if I install a second RTX 3080 instead of the GTX 1080 TI in System 1, is the speed of the RTX 3080 cards twice as fast as a card?

Hello!

is there no one who uses two rtx 3080 for gpu rendering?

Hello!

Does one RTX 3090 render faster than two RTX 3080s?

If you're only using vray as render engine and it is about Vray GPU rendering, I would wait until Vray GPU works with all features and bug free. Even Hybrid doesn't work error less... This is my experience.
Who knows how long this takes and which Card will be available then..

Hello Wohnraumdesign,

I apologize for the delayed reply.

You can check how a specific hardware component performs in comparison to others in the benchmark results here.
