Triple SLI Titan's not enough for 4k surround

Actually, you'd almost need 4GB with everything maxed in Crysis 3 on a single 4K screen.

That is what I am saying.:)

There is no cards now and probably not even when Maxwell is with us that will be able to run three x 4K screens. Even if Maxwell is 50% faster than the Titans/290Xs it still won't be enough GPU grunt even using 4 top Maxwell cards.

Some of the guys on these forums are using 4.5gb of VRAM on their Titans @5780 x 1080 which is a lower resolution than 4K. With the next gen of games VRAM is also going to be a problem.
 
4k surround is terribly silly. Use 17 million pixels worth of display clarity and GPU processing for blurry peripheral vision...

Isn't Mantle supposed to stack the VRAM? So 2x290's = 8GB - 3x290's = 12GB or have I misread this?

It allows developers to implement their own multi-GPU configs, but AFAIK it's unlikely we'll see stacked VRAM anytime soon. Johan mentioned using 1 card for rendering and others for compute tasks, AI, etc. As opposed to just AFR which we have now. If I've understood it right we could see >2 GPUs become much more prevalent as you could maybe have 2 in AFR and another for purely logic, not drawing anything but accelerating portions of code that are well-suited for a highly-parallel system like a GPU. We have already seen something akin to this with hybrid PhysX, where an ATI crossfire setup could run alongside an Nvidia card.

I don't know that much about mantle but to do what you describe above would change the way CF works.

I just had a look about and can't find anything, so assume me as wrong on that :D

Cheers Tangy. I skipped through a couple of the readings on Mantle and came up with 5. :)
 
Just thinking about the latency involved in accessing another gpu's vram over pcie... you could potentially do it but i cant see that you would ever want to without replacing pcie with something substantially faster

i vaguely remember reading the same thing somewhere but having thought about it i dont think its a great idea, it might be better than running out of vram altogether, but it will still be a hit on performance
 
The problem is fillrate...... There's just not enough of it!

That's why the 290 % 290x beat the Nvidia cards by a decent margin at 4k because they have 25% more fillrate.
 
Am i being blonde, three titans running three screens equals 25-30fps, so one titan running one screen would be 25-30?

Edit ignore me just reread chapparels post i'm being blonde, now where did i put that dye :D
 
If is capable to do so, the R10 series going to fly of the shelves, if there are any Mantle games out :D
