Microsoft Confirms DirectX 12 MIX AMD and Nvidia Multi-GPUs
It's not exactly new news, but Microsoft actually confirms it at this stage. Microsoft technical support states that DirectX 12 will support “multi-GPU configurations between Nvidia and AMD.” Something we call Asynchronous Multi-GPU Capabilities.
This is shown on a screenshot published over at LinusTechTips. No requirements or further details were listed though. With such a setup you could mix Nvidia and AMD cards in tandem to render your games. There is a massive issue though. Lots of the optimization work for the spreading of workloads is left to the developers – the game studios. The same went for older APIs, though, and DirectX 12 is intended to be much friendlier.F frame buffers (GPU memory) won't necessarily need to be mirrored anymore. In older APIs, in order to benefit from multiple GPUs, you'd have the two work together, each one rendering an alternate frame (AFR). This required both to have all of the texture and geometry data in their frame buffers, meaning that despite having two cards with 4 GB of memory, you'd still only have a 4 GB frame buffer.
Microsoft developers stated the upcoming DirectX 12 API could deliver an up-to 20 percent higher frame rate in games and a decrease in CPU utilization as well.

Wouldn't it be fun, if you could either hook up a Gsync monitor to the NV card or a freesync monitor to the AMD, and in both cases it just works, using both cards for rendering. No need to choose anymore. Time for proprietary functionality to go.

Nvidia gonna be flipping mad.
They'll probably do whatever it takes to break cross vendor compatibility.

Why? They are Bad guys or something?
I think it will be fun to have PhysX and Radeon with Free Sync

+1.
They're probably coding it out right now in their drivers...

That doesn't exactly fill me with hope for multi-GPU support..

No, because they don't want people to do stuff like the mix of physx and fsync. They'd rather keep people buying gsync monitors, instead of a cheaper monitor and an amd card to go with it
But relax, most likely we won't ever see this happening in real life. There will be a big fuzz about nvidia blocking it with a simple driver installation flag or something similar, and most likely, cross driver support will be extremely poor anyway.

It's not a particularly official confirmation and it might even be the tech girl misinterpreting the question.
If it is officially supported, I still don't think it's a particularly good idea when SLI and CF still hasn't been perfected.
There is also the issue of installing two sets of GPU drivers that could cause issues.
I'm assuming that also means you could mix two different cards from the same vendor?
Does it also mean the GPU memory won't be mirrored or would GPU mem now be limited to the card with the lowest amount?

Gpu mixing has been attempted in the past with lucid logics and failed, same will probably happen here.

why so much nvidia hate lads? you recon that AMD wants people to buy a top range nvidia card and mix it with low end amd for freesync to save money? Neither of them will want this and no dev will waste time optimizing games for multi vendor gpu mixes.They have plenty of work without this

I see support from Nvidia and AMD to make it happen but for sure, both brands will ensure that full optimisation advantages require proper sli/crossfire.
Think of the backlash Nvidia will face if they block this feature. It will cost them alot I think. At the end of the day, they may be one of the greediest brands in the world today, but they are still at the mercy of the consumer!
And I dont see the point in making comments about fan boys. Fan boys still only make a small fraction of their customer base. If they support this, they may see a rise in sales from AMD owners purchasing mid range cards to utilise physx.
