different gpu's: can it work?

[MetalHolic]

first of all, hi I am new and my English isn't that great

my question:
I have 2 gpu's

1= AMD HD8760 2gb

2= ASUS EAH 6850​​

 

is it possible to run these in sli?

if yea, will it make a difference

 

no, why not and why cant different cards be matched with each other?
 

thanks

uh, SLI only works on nvidia GPUs...

You mean Crossfire. Radeon multi-gpu configurations are Crossfire, GeForce multi-gpu configs are SLI.

 

Generally it's just how the drivers are written. AMD's are more lenient than Nvidia on what GPUs you can pair together. With Nvidia the GPU has to be the same model and have the same amount of VRAM. With AMD, you can pair a 7970 with 2GB of VRAM with a 7950 with 1GB of VRAM, for example (if I recall correctly. Please don't yell at me if I'm wrong, anyone).

 

You can try, though. You'll just need a Crossfire bridge to test. I do doubt those two particular models would work as they're a little far apart in terms of generation.

Cross your fingers that developers allow it with DX12, but at the moment you cannot.

but it will not hurt anything?
nothing will break?​

it just won't work

Crossfire will not work between the two cards because the CPU chip between the two are different.

 

The HD 8760 uses a "Cape Verde" chip.

The HD 6850 uses a "Cypress" chip.

 

You should, however, be able to Crossfire the HD 8760 with another "Cape Verde" based GPU

• HD 7730
• HD 7750
• HD 7770
• R7-250 (E / X / XE)

The HD 6850 will only work with another HD 6850, or a HD 6870.

 

 

You won't hurt anything.

The drivers will simply not let you enable Crossfire -- even if you have a Crossfire Bridge between them.

You can, however, run the two in one system simultaneously. They CAN work as two separate GPU's...running their own separate monitors, etc.
