DX 12 and 970

[Guest]

Okay, so as some people might have figured out the questions about DirectX 12 SLI 970. How will that work with the 3.5GB of high speed memory, will the 3.5GB and 3.5GB pair up before the .5 and .5 do? or will will it be 3.5GB of high speed, .5GB of low speed ans 3.5 of high speed and another .5GB chunk?

Is it confirmed, that VRAM will stack? No... so just wait and see is the best answer I can give you, it is 5 days until it comes out

[TheSLSAMG]

If the memory pools as some have suggested, I presume driver optimizations would have it pool 7GB of fast VRAM and 1GB slow VRAM.

[SkilledRebuilds]

Programs read it as a full 4GB, and DX12 will too. Don't think much will change as per stacking, without 7+1 happening.

But how knows

 

Engineering abilities can bring so much to the table in the future.

You know the 970 Gate with the 3.5GB section and .5GB section? Well, how will the two pool together IF VRAM stacks like its rumored to be which will it stack with the faster portion first then the slower portion second or fast/slow/fast/slow AND

I could test it if someone was willing to send me a 970 SC+ACX2.0

for now the best answer is

but until we can confirm this leaving it as unmarked~ If anyone knows any additional info please put it down~

-epic snip-

I ditched my 970 SLI and got a 980Ti, so I wont have to deal with VRAMgate, nor the speculations IF the VRAM will or will not stack

I need to treat myself to a 980Ti Hall of fame after I get myself a Classic Vibe 50's Strat and Custom les paul

I got the reference EVGA Superclocked, I like the sexiness of it

I should do the same, I just need a place to sell them to pay off some of the 980 ti cost.

I sold them on a local site similar to Craigslist for 550€ both, and got the 980Ti for 650€ (price without VAT) so that is a fairly good price

Kind of scared to sell them on craigslist, basically have both my cards sitting in my case with none of the games I play utilizing them.

I'm keen to see what happens with DX12 and SLI, I spec'd my PC for two 970's got the one, if it works out than sweet I'm going 970 shopping, If not ive got good enough performance and will wait for two more series and than go again for the "70" in that range.

So is D12 gonna slow my old ass craptop down even more?

Try reddit's /r/hardwareswap. You should be able to get $270-$280 USD for each card.

Heyyo,

Just a heads up btw... current NVIDIA drivers do NOT support SLI in DirectX 12.. so it's not even possible to test them with anything, even 3DMark's API Overhead test. It just crashes as soon as it tires DirectX 12 with SLI on.

I just hope it works out that way... my 2GB VRAM GTX 680 Two-Way SLI setup is really hurting right meow lol... I needs more VRAM.

It's not even confirmed if the VRAM sharing will be part of DirectX 12 API's foundation... OR, if support for it needs to be added much like current AMD CrossFire and NVIDIA SLI to the game engine... a prime example of a game engine that doesn't work for multi-GPU at all? Unity Engine. Not a single damn game on that engine works with SLI properly... probably same for CF I'd imagine... so I bet the developers, Unity Technologies will once again ignore enthusiast PC Gaming rigs if that's the case...

The opposite good sir. If your GPU supports DirectX 11 and thus the foundation of DirectX 12? Then it will see a minor performance boost. The main reason is it takes the draw calls away from the CPU and puts it to the GPU thus the CPU is freed up a little to focus on other calculations.

If those Andantech benchmarks of the unreleased DirectX 12 Star Swarm are any indication? Weaker CPU computer builds will see a better performance boost than enthusiast systems. That chart shows decent gains with the AMD APU which is a prime example of lower end PCs seeing a little jump upwards.

Heck, even Intel CPUs using the iGPU gets a boost... a very minor one though since Intel iGPUs suck lol.

Of course, Anandtech also did some discrete GPUs but on the AMD side? I'd take those results with a grain of salt for comparing to DirectX 11 as there's definitely some bugs... the NVIDIA GTX 750 Ti should not have scored higher than the AMD R9 290X in DirectX 11 lol.

This is what worries me.. My cpu is more than capable of handling its own.. But only have a 1gb 610m in the craptop.. I think I'll keep it where it is and wait to do any gaming on the desktop upon completion haha

Fair enough, but so far DirectX 12 has impressed me from my initial runs on 3DMark API overhead test... of course, it only benchmark's draw calls per second and not 3D performance so I've yet to see how it translates into raw performance.
