Both Mantle and DX12 can combine video memory

o-O

if true this will make SLI users cream

If this is true and not just a marketing ploy, wouldn't this also work on any crossfire or sli setups done with two physical graphics cards?

Oh, now they want to bring in their hbm and dual gpu cards I think. 295 sales might gain a bit momentum and, who knows, maybe a 385x or something.

We will see if this really works the way he pointed out.

Bring it!!

Quad TITAN's standing by to stack some memory.....! Just hope they don't pull one over on us about how this is just for the newest brands and no backward compatibility with us guys with the older hardware.

Please do not be another marketing rep blowing smoke attempting to rattle the cages of us hardware freaks that are out there.

We shall see if what he says really works. I've seen a lot of claims over the years by different companies that turned out to be BS. Cautiously optimistic.

I still will not go multi gpu even if this is true, the issues with games not supporting sli or doing it poorly are too great imo. I am biased as I had a nightmare 9 months with a 5970 back in 09, poor ati drivers + terrible xfire support in the games I was playing = RMA and lots of rage I cannot go through that again (first world problems)

Last Civilization: Beyond Earth use allready SFR with Mantle..

http://www.anandtech.com/show/8643/civilization-beyond-earth-crossfire-with-mantle-sfr-not-actually-broken

Thankfully, AFR is not the only approach to multi-GPU. Mantle empowers game developers with full control of a multi-GPU array and the ability to create or implement unique MGPU solutions that fit the needs of the game engine. In Civilization: Beyond Earth, Firaxis designed a "split-frame rendering" (SFR) subsystem. SFR divides each frame of a scene into proportional sections, and assigns a rendering slice to each GPU in AMD CrossFire configuration. The "master" GPU quickly receives the work of each GPU and composites the final scene for the user to see on his or her monitor.

/QUOTE]

Ofc, in the case of SFR ( split frame render ), developpers need to put more time and work with it, compared of fix some few problem with AFR ( texture / light flashing, scaling )

Yeah I hear you....... Does sound a bit fishy as both GFX card companies have truly addressed their concerns on stacked/unified RAM architecture and how they plan on introducing it to the public. All in due time I suppose.

Makes me feel like my kids on Christmas, or something........waiting ever so patiently to find out what the companies are going to give us.

Seeing that even if I added a second 970 to my rig, I would still be under the power restraints that is the Mac Pro and the silly power connectors that comes with it. I would add a second one no problem if developers did use this API.

I would have more than 4gb of memory then!(Joke)

Soon as the games hit 6-8gb of vram, your quad titan's, even if they scaled at 100% full speed, your cards, all 4 of them, will be on their knees, 8gb vram???, forget it.

maybe 6gb vram and settings,etc but at full 8gb vram? 100% even with 4 980 gtx's oc'ed, will be on their knees.

5-6gb sounds good, over that, our cards ain't fast enough to do something like that yet and maintain very high fps at the same time.

LOL, and LG is talking about 8k resolution this year? PLEASE!!

Games wont move period at that resolution, as of now no, OLD!! games perhaps, Today's games? FORGET IT...

If people own 4k, Try maxing out with dsr, should give you a hint how fast it will move, lol.

5gb sounds perfect.

Shoot, playing farcry4 @ slightly over 2560X1600 res(DSR), + maxed out settings + nvidia inspector 2xmsaa + 2xSGSSAA, sucker is moving like 17+fps to 20+ fps, seems to moving alright, looks great, lol.

I cant imagine running 8k with farcry4 with everything maxed out @ 60fps, holy good god moly, thats NEVER going to happen for a LONG LONG TIME.

As of the Mantle+DX12:

All I got to say is this, its about time, how many years later and still haven't found out a way to stack the vram? I knew it was just a matter of time, good god about time, I wonder when this will be coming out in full force? I don't expect anytime soon.

Matter of time before Nvidia comes up with there's, lol.

But there is a catch, games will specifically have to be designed to take advantage of it... So, imo it will be very rare

Be better for 970 users, as they'll have 7GB

#5006849 Posted on: 02/03/2015 05:31 PM

Still way better for 290x 8GB users, as they'll have full 16GB!!!11one

No just no.

We will still have full 8GB memory.

But what this will do is be amazing for no hitting that 3.5GB wall that a lot of people are seeing.

I don't see this at all I have hit 3.9GB and not had issues. Same over at PCPer who have tested BF4 at 6K resolution and only found the 970 to perform around 12% slower than the 980 and they too did not see any hiccups.

This will essentially increase that wall, not just for 970 users but for everyone.

This HAS to be made compulsory for devs if your game uses a lot of memory!!
