Yeah I get it,because AMD runs 100-40 in dx11 that's why it must be a better dx12 card...
/s
It could have gotten another 20% boost on top of what kind of performance it have if it has aces, but it doesn't have those. so no 20% boost it could have. understand ?
100+20 is more than 100, but 100+ 40 is even more than 100 and or 120, get it ?
Interesting. This was already delivered by Mantle API back in 2013. Back then Folks didnt care for the Performance boost on weak CPU. Especially green team cheered that there was only low Performance boost in graphics limit. Seems like the tides and metrics changed?There is plenty of performance boost with nvidia in scenarios for which Dx12 was made,small cores vs huge GPUs,look up the benches,of course you don't get a boost when you bench with a single core monster that just brute forces though everything on a single thread. (dx11)

Such bad dx11, much wow.

yeap because games with gameworks are the best example to measure a card potential D:So? 20% worse for any single card..in 1440.
You better go search for some 4k benchmarks for single thread games like bioshock.
3% less stock vs stock, and the furyx isn't the only card amd makes. i don't need anything more to make my mind here, or should we include Aots ,dx12 too to show nv'd weakness ? no that would be unfair right ?So? 20% worse for any single card..in 1440.

I think the 1080 will impress more on release. I expect more out of it with proper drivers, too.
I think NV pulled a bit of a surprise with the clock speeds as well.
Please! I hope you're not implying nVidia actually underplayed the 1080's performance, the would be so unlike them. They are the king of the mountain when it comes to hyperbole and playing up their products. If anything nVidia would have accounted for future driver tweaks in their little performance chart, which by the way, gave no indication as to which games were tested.
I tend to think the stock 1080 will actually do the opposite and regress in real life to something like 10-15% over 980ti.
People seeming to only want to compare to nVidia's last generation but how will Pascal fare against 390X and Fury? Do you really think it will top FuryX at 4k? Notice how nVidia put VR in the spotlight and not 4k? I would think someone spending $700 on a video card would want 4k performance over anything else...

FuryX competitor would be a 1080ti, I would think?
1080 would be in the 980 spot. One notch below the top dog card level.
We haven't seen the 980ti counterpart yet, the 1080ti.
Nevertheless, I think the 1080 will be more impressive as time goes by.
"What makes it so fast"
Nothing. This is the most lackluster new GPU released on a new node (a full node jump no less) in the history of GPU's.
Nvidia already flops to amd at 4k in both single and multicard situations. Nvidia's terrible sli scaling needs to be fixed but it seems Nvidia is putting even less resources on that end. However if amd also follows then it gets interestingThat's a stretch.
I wouldn't bet on it.
I spend tons of money on graphics cards and I don't care about 4K. I have 144Hz 2560x1440 monitors and I want to take full advantage of them.
If you care about 4K and if GTX 1080 ultimately flops at 4K (doubtful) compared to AMD Fury, then I would recommend buying AMD Fury.

Nvidia reckons the SLI HB bridge doubles the maximum theoretical transfer bandwidth in comparison to current generation Maxwell architecture when in SLI. This obviously helps in the speed at which the two graphics cards can communicate and share data with one another, in theory leading to smoother frame times and better SLI scaling.
The downside is that this particular Nvidia branded bridge is only going to be available for its GeForce GTX 1080 graphics cards at the moment. No dice on the 1070s at the moment, but a standard SLI bridge will still suffice. I’d guess from Nvidia’s viewpoint they’re thinking if you want more power than a 1070 then you’re probably going to opt for a GTX 1080 anyway.
This is the confusing part. They are the same die, one full, one cut. How is it possible to have 3 & 4 way SLI on 1070 and be limited to 2 way on 1080 no matter if the single bridge is used?http://www.game-debate.com/news/?news=20148&graphics=GeForce%20GTX%201080&title=Nvidia%20SLI%20HB%20Bridge%20Doubles%20GTX%201080%20Transfer%20Rate%20For%20Better%20SLI%20Scaling%20Performance
So nVidia has done an interesting thing here and beefed up 1080 SLI while 1070 makes due with their older version.

Do you know that the 1070 models will have greater than 2 way SLI?

this entire sub forum, you, glo, and rs posts the most informative posts :thumbsup:
Bolded part is not true.
The Maxwell cards do have Asynchronous Compute Engines - they just aren't as good at it as AMD cards are. No reason to suspect Nvidia would remove them from Pascal.
EDIT:
Look at the table near the bottom of this page.
No I'm not sure about that. Seems like nVidia may be artificially differentiating the 1080 this way by locking out the 1070. Maybe its unlockable? Or could be actual electrical traces on the PCB that only the 1080 has.
Still though, its interesting to see a supposedly faster version of multi-gpu.
We could be left with the interesting situation where a 1070 4-way SLI is a lot faster than a 1080 2-way SLI, and close to the same price.I think that NV actually has a real limitation with SLI HB. That link states NV is doubling the SLI bandwidth but yet it's only limited to two 1080 cards. We know that a 1080 has 2x SLI fingers. It's highly likely that NV's new SLI HB bridge is getting 2GB/sec because it combines both of the SLI fingers on 2 cards.
Since the cards require 2 separate SLI fingers working together to double the bandwidth, if you introduce a 3rd card, this type of setup wouldn't work. It means there is no flexibility at all in this type of an arrangement.
It also means old SLI bridges won't work without a performance penalty; and of course NV will start selling these upgraded SLI bridges for a fee. In AMD's case, the upgraded XDMA was a free feature. :sneaky:
What makes it worse, is you have to buy a new SLI bridge depending on the mobo you have because it's not PCIe.
$70/100 premiums for reference coolers + $20-30 for SLI bridge, it all starts to add up. More $$$ to NV, less flexibility to PC gamers.
It's also not as easy anymore to just buy the new SLI HB bridge. Because they are rigid and larger in size, you have to do research as certain after-market cards may not have sufficient space between the SLI fingers and the extended AIB heatsink.
AIBs will need to think carefully now about how they design after-market heatsinks to not interfere with the rigid SLI HB bridge.
SLI BRIDGE (1st gen)
What is the function of the SLI connector?
The SLI connector is a proprietary link between GPUs that transmits synchronization, display, and pixel data. The SLI connector enables inter-GPU communication of up to 1GB/s, consuming no bandwidth over the PCI Express bus.
http://www.geforce.com/hardware/technology/sli/faq
By deducation then => SLI HB = 2GB/sec
vs.
AMD's Crossfire Bridges were limited to 0.9GB/sec:
"In AMDs current CFBI implementation, which itself dates back to the X1900 generation, a CFBI link directly connects two GPUs and has 900MB/sec of bandwidth." ~ AT
Year 2013 AMD XDMA = 16GB/sec
Shockingly after introducing NV Link, NV's Pascal GP104 has 8X less available bandwidth between 2 cards than AMD 2013 XMDA does. This means AMD has more available bandwidth even in Quad-CF on an X99 platform or Z170 platform with PLX chip than NV has on a dedicated SLI HB bridge with 2 cards.
If PCIe 4.0 comes out, AMD's bandwidth would suddenly jump to 32GB/sec!
Thanks a lot! I am nowhere near as knowledgeable as some of the guys on this forum who deeply understand GPUs. I actually have to research and read up on the technology before I post because often I don't even know how the technology works. I am not an electrical engineer either and don't work in the GPU industry. What I do have is pretty good memory which allows me to find key information quickly since I recall reading it on website ABCD for product XYZ.
If you have the interest in tech overall, there are a lot of great articles that help learn. For example, just stumbled on this so I'll read it to see if I can learn something new.
Basically, what NVIDIA have done with Pascal is overclocked Maxwell and split the SMs into two in order to boost compute efficiency. This will help push Pascal past the FuryX with ease under DX12 scenarios.
The question is, what about Vega? Vega will be quite a boost over Fiji.
We know that Polaris is only a mainstream GPU. It likely won't be competing in the same bracket as the 1080. Heck it might be closer to a 1070. Vega, on the other hand, will have two variants. Vega 10 and 11.
Seems to me that buying a 1080 is a huge mistake as AMD have pushed Vega forward to a Sept/Oct launch. If we assume mass availability of the 1080 by July then 2 months later we're going to have a GPU which will bury the 1080 with relative ease. All Vega needs to do is bump up performance by 5FPS over a FuryX in AotS to beat a 1080.
OF course there are other games but I don't see NVIDIA retaining the performance crown for long. Even if they release a 1080ti.
If Polaris 10 can deliver better than 390x performance despite using GDDR5 on a 256-bit bus then we're looking at Vega being quite powerful.
We haven't seen Pascal reviews, we haven't seen Polaris reviews, and AFAIK AMD has yet to go on record with Vega being a 2016 release, yet you reckon 1080 is a bad buy. You built so much credibility on this forum by patiently explaining how GPUs work, how (DX12) features are implemented and how they affect performance, and now choose to spend it lavishly on unsubstantiated claims.Seems to me that buying a 1080 is a huge mistake as AMD have pushed Vega forward to a Sept/Oct launch.
