Simple questions regarding SLI and Crossfire.

Thread Starter 
Let's say, i5-3570K, it has integrated gpu that is Intel HD 4000 and I also have HD 7850. Can I crossfire HD 7850 with Intel HD 4000?
I heard that you can crossfire AMD GPU with integrated gpu of AMD CPU? Can you do the same to integrated gpu of Intel CPU?
Last question, what is the maximum number of gpu you can actually sli or crossfire together?

Thanks. biggrin.gif

You cannot crossfire an AMD GPU with an Intel integrated GPU. Crossfire is an AMD proprietary technology and as such, only works with AMD GPUs. The same is true for Nvidia's SLI technology.

The maximum number of cards that can be in one SLI/Crossfire setup is 4.

The same thing goes to AMD integrated GPU?
By the way, what AMD CPU that has integrated GPU and what is the latest integrated GPU from AMD?

Thanks for clearing my doubt. smile.gif

No, you have to have an AMD apu and an AMD video card to crossfire.

the A10s are the highest end right now

"APU" is AMD's marketing term for their CPU's with integrated GPU's. However, the GPU within the APU's are much more powerful than any of Intel's current offerings, equivalent of an entry-level discrete graphics card. It is possible to CrossFireX the GPU within the APU to a discrete GPU with something called "Hybrid CrossFireX", but there are only a few GPU models you can do this with. I can't recall these models off the top of my head though.
