Crossfire R9 380, and R9 390(or better) in future

Since I don't have the budget right now to get more than R9 380, I will add R9 390 triX in the future or a better one (if there's available AMD Radeon GPU)

I am wondering if R9 380 can be crossfired with R9 390? regardless of brand, clock speed, VRAM and ETC

 

 tnx  :)

Nope. You can only Xfire R9 390 with R9 390. Brand doesn't matter, but you need the same series

the 380 is a GCN 1.2 card and 390is GCN 1.1. The only cards you can XFire with a 390 are the 290(x), 390(x) and the 295x2. The 380 can only be XFired with another 380 or the 285 it was based on.

I cannot be held responsible for any bad advice given.

I've no idea why the world is afraid of 3D-printed guns when clearly 3D-printed crossbows would be more practical for now.

My rig: The StealthRay. Plans for a newer, better version of its mufflers are already being made.

Has it actually been confirmed now that you can xfire a 390 or 390x with a 290 or 290x? If you look on AMD's site the chart they had on there didn't show the new cards as compatible with the older ones...

Even if it was possible (which it isn't), it would run at the core count and vram of the 380. You might as well crossfire 2 380s

Don't they? Normally AMD allows CF as long as it's the same generation GPU

Yes its been confirmed. Don't have the link to it.

 

AMD cards can CF with cards of the same architecture. Clock speeds, memory doesn't matter. 

 

As of today the r9 390 can only CF with r9 390, r9 290, r9 290x, r9 390x.

Good to know, cheers. So now I can rest easy when I buy a 390 (black friday deal lol) and CF with my 290x

tnx...

I saw that 

Gigabyte R9-380 G1 

doesn't have port for crossfire bridge, is it true that they don't require crossfire bridge (inter connected at 2 way GPU on-board)

Since the 290 all communicatins for crossfire go through PCI express, I think. No bridge needed anymore.
