Can you crossfire a gtx GPU with another gtx GPU (same series cards)

[spaghettea]

First, can you even run a non AMD card in crossfire? Second, if I had a GTX 1070 and a GTX 1050ti, could I run them in crossfire. Regardless if it doesn't work well. Will crossfire work? I haven't been able to find a definite answer to this.

CrossFire = AMD
SLI = nVidia.

Serve the same (basic) purpose.

*Can* you SLI different nVidia models..... no.

SLI has to be supported, which on the 10 series cards starts with a 1070 (no SLI support in a 1050/TI/1060) - and for SLI they have to be the same GPU chip at their core.


What you can *potentially* take advantage is EMA (Explicit Multi-Adapter) within DX12 to utilize two differing GPUs (can even be cross brand), but widespread adoption/support is lacking. The only title I know of that can benefit with the use of EMA is Ashes of hte Singularity.

Another option is to use another card as a dedicated PhsyX card - but similarly, games that benefit are few/far between and, depending on the specific cards used, can actually hinder performance, even in games that support it.



tl;dr SLI is nVidia's equivalent. No, it's not going to work.

Thank you for not just saying "no". That's what I thought, but couldn't find it explicitly stated anywhere when i'd search it.
Regarding the EMA point, that's something I never considered and yeah support for that, if possible, would definitely be lacking. Cross-brand support would mean profit loss for manufactures, which they kinda have the GPU market in their pockets right now. Either way, i'm going to look into both of those out of curiosity.
