Crossfire question

[Lonewolf33651]

Can you crossfire an r9 270x with a r9 280x?

[Flavortown2k16]

No, you can use the multi gpu thingie prob(not really sure abut it)

[Coaxialgamer]

Not crossfire,  as you need the same gpu,  but ypu could use it in dx 12 games that support EMA

If they are the same Architecture they can crossfire.

You can crossfire only within the same chip family, so if you have a HD7950, HD7970, and R9 280, those would work.

for amd yes you can nvidia no, so yes you can crossfire but both card will act like they are both now R9 270X cards now since it will always be running at the slowest cards speed and spec

I don't think it would work as the 280x is from the tahiti family and the 270x is from the Curaçao XT (Pitcairn) family group. The GPUs that I listed are the ones that I personally tested and I know would works with the 280x.

 

Also Nvidia is pickier when it comes to SLI, as they don't even let you mix RAM size.

oh my bad i didn't realize that both cards were from different architectures, when you said family i thought you ment the R9 family but nvm brain fart moment.  for the cards you listed above aren't all of them from the Hawaii and tahiti architecture

The R9 280 cards (Except the R9 285) are just refreshes of the 7950 and the 7970 which is based on the Tahiti core. So if the op really wants to crossfire he could probably get a cheap second hand 7970 and crossfire that. I can understand the confusion as it's pretty hard to tell what AMD is rehashing and what is new sometimes. That's why I prefer to call them by their codenames instead.
