DX12 will allow to CrossFire/SLI

and by the title I mean, to be able to use GPU's of different architectures at the same time.

DirectX 12 will support all of this across multiple GPU architectures, simultaneously. What this means is that Nvidia GeForce GPUs will be able to work in tandem with AMD Radeon GPUs to render the same game – the same frame, even.

This is especially interesting as it allows you to leverage the technology benefits of both of these hardware platforms if you wish to do so. If you like Nvidia's GeForce Experience software and 3D Vision, but you want to use AMD's TrueAudio and FreeSync, chances are you'll be able to do that when DirectX 12 comes around. What will likely happen is that one card will operate as the master card, while the other will be used for additional power.

you know what it'd be truly cool too? For one to be able to use the GPU in conjunction with the integrated card on every fucking Intel CPU. Because it's stupid that with recent Intel HD's becoming so efficient that they have no use other that wasting energy when the GPU is engaged.

I remember the Hydra chip,good times.

Maybe they'll used this feature on the Xbox

I'm really wondering how APU's are going to fair with this new set up. Haven't seen much on what that means for these new chips. Currently I wouldn't recommend but I could see them being useful in a setup such as this. Like offloading physx onto the APU's GPU section of the dye or other similar setups.

dx 12 support stacking vram and cross brand sli ,it's time to upgrade my gpu

lol what does it matter, pc doesn't get complicated gfx anymore.

i can only imagine the bugs and performance issues related to this, no ty.

AMAZED that it took this long for a thread to be made about this on here. everywhere else the story of this being a possibility its making ripples. it would be a monumental achievement for pc gaming. but it takes damn near a full day for a thread to be made about it on here...what happened to system wars maannnn, lol smh.

you should probably change the title to DX12 will let AMD and Nvidia cards work together, because the title sounds like DX12 is simply just supporting Crossfire and SLI which when I read I didn't think much of it.

Is not that DX12 is awesome is that DX has suck for generations the problem.

There is not a single reason why if you have 2 GPU with 8GB of memory total you could only use 4Gb,it is obvious that SLI and crossfire have been broken for more than 2 generations and MS did little to fix it,i find odd that it isn't until AMD step in with Mantle after criticize them fro years that MS want to do things right.

Is one of the reasons why monopolies hurt the industry..

It was done already several days ago but it die quickly and pass to second page.

That's very interesting. Of course it all depends how much AMD and Nvidia are willing to play ball.

OpenGL didn't do any better i.e. GLnext to fix it's own issues.

As if Microsoft started with DX12 after Mantle was announced. Laughable.

Well Mantle wasn't make in 1 day and yet by the time DX12 land Mantle will be close to 2 years,so yeah Mantle not only landed first it was probably on development for a long time,AMD has years complaining about DX over head and latency.

But i didn't say it Opengl did any better,fact is the standard was Dx not opengl,and even so in things like lower CPu over head bundles,PRT opengl has been ahead of DX.

Lets not forget how MS has time after time put the foot in front opengl to sabotage it,just like did with Java.

Mantle is dead. Long live DX!

You were thinking what I was thinking. How did this happen?

really?? i missed it. could you send me a link for it? i'd appreciate it, thanks.

(not that i'm doubting you...i'd just like to look it over)

I have 2 gtx 970s in sli. If direct x12 will let the memory stack that would be amazing. Im skeptical about the amd/nvidia mix of cards in one system. It just seems like a driver/coding mess. But if it works thats awesome!

Pretty sure it becomes disabled. You can even do it yourself from the bios.

I'm more excited about the Vram stacking. 7GB will be enough for quite some time

@HalcyonScarlet:

It always stays "on" because the CPU and integrated are both part of a SoC. You can disable it all you want in the bios but it still consumes energy. In this case, a lot more energy since the GPU will always be on too. On top of it the integrated is the only one with connection to the screen when you're on a laptop. Both the HDMI-out and main screen are tied to the integrated.

Even if it is on, it would be in a completely idle state and would be using very little.

@Gue1:

Disabling Intel IGP would disable Intel QuickSync.

Let's us not forget the following

1. AMD's OpenGL PRT extension is dead and vendor neutral version was later adopted. They are not compatible and AMD haven't fix a bug with this extension.

2. NVIDIA's OpenGL for lower CPU overheads extensions doesn't work on AMD and Intel GPUs.

3. OpenGL still has multithreading model issues i.e. another single thread legacy.

GLnext fixes multithreading model and vendor specific issues with GPU vendor neutral APIs.

From Apple

The above OpenGL multithreading model looks familiar to DX11 multithreading model...

This is great news. I'm excited about the Vram stacking possibility.

And yet DX12 will be done in June 2015 or fall 2015 latest. And where is Mantle today? Still in beta with no end in sight. Not only that, it's an API that works only on AMD. DX12 works on AMD, NVIDIA, Intel, and ARM (Qualcomm). Not only that, totally new hardware is required to get the full Feature Level 12 of DX12. So how is it that MS is able to create an API that's vastly multiplatform more than AMD - all of that in a year after announcement of Mantle?

The tiny gap between AMD's Mantle and DirectX12 results on AMD GPUs indicates common software driver technology.

Crossfire? SLI? I told yall from the beginning on why the system is split in two. Next up is using the 8gb of flash as NVRAM

Even if Nvidia fucks with this and somehow stops AMD and Nvidia cards being cross compatible it'll still be greatly useful for hanging onto older cards rather than selling them.

wat

@Tighaman: Yeah MS is way smarter then people think. Wonder if DX12 would allow you to link Xbox one's together for extra

Processing power?...would be awesome!

NVIDIA will disable it just like they disabled physx when an AMD gpu is detected. AMD will likely do it as well. However, I feel like this was a misinterpretation. I thought they meant SLI and X-fire with different arch as in SLI with kepler/maxwell or hawaii/tonga/pirateislands.

My thoughts as well.

@Link3301:

lol yeah my post was vague....half my post got deleted for some reason. So if DX 12 allows you to link multiple GPU's together making them act as one powerful sing GPU. Why couldn't they make a GPU or processing devise add on for the xbox one?.....or possibly link multiple xbox one's together for extra processing power? The ethernet port goes directly into the main SOC so theoretically it should be possible.

@magicalclick: Wasn't being sarcastic....

if Sega has showed us something is that this kind of stuff always fails. Although there's the argument that the market is different now....

@Gue1: Yeah that's true. I think it could work as an add on that came with your game....say like Halo 5.

Combining multiple consoles would be such a waste of money. You would only be combining the GPU horse power of 2 or more consoles just for the GPU (which is equal to a 75 dollar GPU). The xboxone wasn't design for this scalability and does not have the bandwidth connectors to make it work. You are better off building a windows 10 system for a fraction of the price.

You obviously have no idea how crossfire or SLI works then.

smells like misterxmedia

lololol I always love el tormo, *finds anti Microsoft propaganda site, copy and pastes without understanding anything*

@stereointegrity: its always mxm when its not agreeing with Cowboys

but u post here the shit he posts on his blog....

@stereointegrity: I post my own conclusion from what i read and find everywhere and thats not from his blog thats reading the purposes of NAND RAM

Actually bringing this back because I'm ordering my PC in less than 48 hrs. Is VRAM going to stack.

Mantle probably isn't what spurred on DX12's optimizations. And they didn't have a monopoly (OpenGL).

But the market needs have been changing for quite some time now, and there are tons of ultra portable laptops with under 2.0ghz processors. There's a large market need for better utilization of hardware in the portable market.
