    Questions on having Multiple GPUs

    Posted: 02 Jan 2020 11:08 PM PST

    I am considering adding more GPU's to my Deep Learning build. My build already has the Gigabyte TRX40 AORUS XTREME motherboard, AMD Threadripper 3960X CPU,and a single Gigabyte GeForce RTX 2080 Ti 11 GB TURBO GPU. But I now want to add more GPU's. Ignoring the cooling (yes, single blower for more GPU's and liquid cooling is preferred) and power (this need a big PSU to power it all) how does the PC handle more than 1 GPU?

    Can I just simpley plug in another GPU and have it work (I guess my mind is hardware wise but if it's impossible software wise that's important too) what about 2 or 3 more GPUs? After all, my motherboard has the slots for them.

    I've read up on this and see that Nvlink is discussed. Doesn't this only connect 2 GPU's together? What happens if I connect 2 GPU's and then add a third one, will this third one not even be used then? How does it work if I connect 2 sets of 2, does the computer just only use one pair?

    Assuming that I can add more GPU's, can I add different ones? Like the 2080 TI and 3 titan RTX? Is there any mix and matching that I can't do?

    What's the difference between Nvlink and SLI?
