gpu? 3060 + A770 in one system?

Perc30_forPrez · February 5, 2023

Wassup peeps,

just wanted to know if it’s possible to do a dual gpu pc with different gpus? Why you may ask? Cause I currently run my 3060 to 3 monitors and one hdmi to 2nd pc which is recording.
Id like to have the 2nd GPU to either dedicated recording of the first gpu or dedicated extra DisplayPort for VR headset and maybe a monitor for stats? I was also thinking of adding a mod to my case and having a screen there so maybe a port dedicated for that as well.

is this a reality?

I see no reason why not, its exactly the same principle as running an iGPU and dGPU at the same time. I'm not sure how good the Intel drivers are for the use-case though. Hardware encoding probably has more overhead if done on a different GPU as its having to move the frame buffer over PCIe between the cards, and your second GPU may have to go over the chipset lanes, so might be worse than just using the same card.

Latest drivers (31.0.101.4091) made AV1 recording actually work on my ARC A770 LE (before it would create an unreadable file if I used AV1, had to use H.264 which chugs). Although I am using the A770 as a main GPU and recording with the built-in feature in Intel's control panel. I know some people use the A380 as an encoder for a stream PC, but that's a separate PC from the one they're gaming on, so I don't actually know how encoding on the GPU in the same system goes. I would assume PCIe resources won't effect the encoding bit much as it's not very bandwidth intensive.
