Two Video Cards (gtx+rtx ???)

in Technical Help (nuts n bolts)

Hello!

My current set up has RTX2060 8Gb gpu but also I have my old GTX1050 4Gb.

It looks like a good idea to add about 700 CUDAs but will it be a really good idea?

I know about VRAM limit. But what I don't know if new card used some RTX features that help it work even better and won't RTX slow it down?

    Each card is handled separately, so if the 4GB card has to drop out due to memory then 8GB card will still keep going. How much of a bost the 1050 will give I don't know - it isn't just about core count when comparing across generations - but I would think it might help noticeably.

    If your system can handle the watts, there's no reason not to. I have a RTX2080ti and a GTX1070ti and they both run together fine.

    Yeah, power not a problem. Thanks, now I see it's working configuration. Just wasn't sure if gtx and rtx technologies work together in Daz.

    The only problem I had with GTX 970 and RTX 2070 is the former fitting in the case.  I don't recommend my solution (a pair of pliers and a now bent drive bay in the case).  Otherwise they work well together and will reduce your render times noticably (disclaimer as always is scene complexity).

    After tests I can say it works fine. Also if a scene more 4gb then only one card works and it doesn't skip both GPUs as I was afraid.

    But bad news is that second 1050it not really helps a lot, it adds 15-20% more iterations at the same time. Not really impressive.
