can you crossfire a r9 270x with a r9 270 and they are also different brands

Yes, but don't do it. The R9 270 will nerf the R9 270x by quite a bit. It would be like having R9 270 CF. And yes, you can crossfire across different brands.

You sure can. AMD is far more forgiving when it comes to mixing for crossfire but as it was mentioned the faster card will slow down to match the slower one so keep that in mind.

? *Sigh* ... first to respond with exact same post as second user, and don't get best answer ...

It happens to me pretty often also to the point sometimes it makes me laugh.

I know what you mean This is the third time in 18-20 hours!

There were two answers and I was like "which one do I choose" and then I thought first come first serve. Then I actually read the posts again and I felt that I slightly disagreed with the first post. It was the bit about saying [Definitely as opposed to maybe] not to do the crossfire that I sort of disagreed with because I think you can overclock the 270 and the 270x and they are very close in performance and the 270 actually outperforms the 270x when both are overclocked sometimes. It is a bit unfair on you because I never talked about overclocking.

Anyway I am sorry if there has been any injustice and I appreciate you taking the time to answer my post 🙂

Haha you can choose whichever you like, it's up to you There is actually quite a bit of difference between a 270 and a 270X due the amount of stream processors on each chip. Even when overclocked, you cannot account for the difference between the two cards regarding this matter. Also, I have never seen a 270 oc'd outperform a 270x oc'd (when done correctly of course). Basically I am just stating that the number of stream processors will be cut to match the 270 when in CF, which will affect performance, especially at higher resolution.

I am sorry to come back at you like this elneelo. The 270 and 270x have the same stream processor numbers as far as I can see on this:

I don't quite know what I am talking about tbh when it comes to technical things like this. But whatever a stream processor is, it appears that some form of the r9 270 and r9 270x have the same number.

Here is one comparison I pulled off the web where (both overclocked) 270 and 270xs performed equally with the 270 outperforming the 270x on many benchmarks strangely. I wouldn't trust this analysis though because he seems to draw the wrong conclusions:

Don't be sorry, I am the one who is incorrect here. I always forget that it is the 280 vs 280x that have the different number of shaders, not the 270 vs 270x. Thank you for pointing this out

With the same number of shaders, a crossfire won't matter too much, just get the clock & memory frequencies to match

Not to worry we have all made this mistake at some point or another. I was bidding on a 270x on ebay but someone beat me to it. Thanks for the advice
