Thanks. So is the founders edition 100 more just because it's available earlier? Was hoping the 1080'd be no more than 500. Guess I'll be getting a 1070, which should still be a nice upgrade for VR from my 7850.

Wait and see. It looks like that custom designs are available at the same time. At least they dont cheap out on the cooling solution like what they did with the GTX980.

The slightly weird thing is that the 1080 has 9 TFLOPS (almost 50% more than Titan X), but yet it is only 20-25% faster. So based on that you would expect a 6.5 TFLOPS 1070 (6.6% more than a Titan X) to actually be slower than a Titan X.

But then again they did say that the 1070 was faster than the Titan X, so who knows.

Not every game is compute limited. GP104 will have less rasterizer (4 vs 6), geometry units (20 vs 24), less rops (64 vs 96), less TMUs (160 vs 196) etc.

The rasterizer and ROP ratio you listed is even lower than the GFLOPS ratio though (66% vs 72%), so if the performance hit is less than this it would indicate that the main bottleneck lies with the geometry units or TMUs (based on your numbers).

btw, do we even know what the exact specs of 1070 are, or are you just speculating?

About the reduced IPC: No progress on IPC doesn't mean no design changes from Maxwell. It's entirely possible that they spent some of their IPC to make it clock faster. The speed demon/brainiac tradeoff is a real thing.

It could be the memory is holding it back. This has less bandwidth than a titan x, but there is potentially 40% more tflops on the card.

Nvidia has removed the GTX 980 Ti & GTX 980 from the list, effectively they're EOL and discontinued. Once the 1070 ships in June, the GTX 970 will be removed also I guess.

 

[finbarqs]

damn... in the middle of my build... still have a GTX 780, but anything @ 3440x1440p is impossible to run... except movies... GTX1080p still seems like it's not the card I'm holding out for... need big pascal... I need something to hol dme over I suppose... perhaps I'll jump on the GTX 980ti when the prices plunge into affordability and I'll just ebay it when big pascal comes out...

 

[R0H1T]

And hopefully 1070 doesn't have the slowass RAM for the 0.25GB (or was that 0.5GB?) fiasco like the 970 did.

Make that 1GB with a node shrink :sneaky:

Rumor: Nvidia Pascal launched at Computex, and will go on sale in June
Geforce GTX 1080/1070 can be found in stores within a month!



www.nordichardware.se/nyheter/rykte...s-till-computex-och-borjar-saljas-i-juni.html

According to NordicHardware:
- Press event in early May, detailing the cards (Editor's Day?)
- Sharp launch in time for Computex, with retail availability
- Data and test samples with reviewers shortly after the press event
- Reviews ready in time for Computex
- Custom VGAs available only one week after official launch
- Work on the VGAs is almost done, now preparing delivery to distributors and retailers
- Focus on performance per watt and performance crown

Looking back, even though this wasn't that long ago, it seems NordicHardware is so far spot on with this... I hope they are right about reviewers getting their cards soon too, better chance of leaks and "accidental" premature published articles.

ooooooo, gon get me 2 o them 1080s I thinks....

 

[Sweepr]

- Geforce GTX 1080
GPU configuration: 1920-2560 CUDA cores (3 or 4 GPCs / 30-40 SMs enabled)
Core clock: >1.6 GHz
Memory: 8GB GDDR5X 10 Gbps - 256-bit (320 GB/s)
Performance: 15-25% faster than Geforce GTX 980 Ti / 50-60% faster than Geforce GTX 980
Price: >$599

- Geforce GTX 1070
GPU configuration: 1536 / 2048-2176 CUDA cores (3 or 4 GPCs / 24 or 32-34 SMs enabled)
Core clock: >1.5 GHz
Memory: 8GB GDDR5 8 Gbps - 256-bit (256 GB/s)
Performance: Similar to Geforce GTX 980 Ti at 1080p/1440p / 40% faster than Geforce GTX 970
Price: >$449

Pretty close.

Geforce GTX 1070's price is certainly lower than I expected. Should become a very popular card if it can match the Geforce GTX 980 Ti @ 1080p/1440p and OC well. And it effectively sets the price ceiling for other mainstream-performance parts (Polaris 10 / GP106).

Bench-life was criticized 2 months ago when they first mentioned Geforce GTX 1080 could be launched as soon as May, but it looks like they got almost everything right:

The new generation of NVIDIA GPU codenamed Pascal degree will be center stage in the first half of 2016, which GP104, which is GeForce GTX 1080 will be determined debut in May. Not too surprisingly, then, NVIDIA CEO Jen-Hsun Huang will be April GTC event, announced Pascal products.

Although the news has been mentioned, Pascal will import HBM2 memory, but the latest data show, GP104 is the GeForce GTX 1080 This card will remain GDDR5, or a faster GDDR5X memory, and memory capacity is 8GB in size. Of course, we can expect higher order GP100 appear, and this is expected to bring HBM2 GPU memory.

...Not too surprisingly, then, PCIe 8 PIN, DisplayPort x 2, HDMI x 1, and NVIDIA GeForce GTX 1080 shipping time DVI x 1 output will be May 27, which is the eve of the Computex 2016. Of course, NVIDIA will start a public way for partners to sell the card, as you want to select various homemade card, it may have to wait until after July.

First post updated.

Five Marvels of Pascal

NVIDIA engineered the Pascal architecture to handle the massive computing demands of technologies like VR. It incorporates five transformational technologies:

• Next-Gen GPU Architecture. Pascal is optimized for performance per watt. The GTX 1080 is 3x more power efficient than the Maxwell Architecture.
• 16nm FinFET Process. The GTX 1080 is the first gaming GPUs designed for the 16nm FinFET process, which uses smaller, faster transistors that can be packed together more densely. Its 7.2 billion transistors deliver a dramatic increase in performance and efficiency.
• Advanced Memory. Pascal-based GPUs are the first to harness the power of 8GB of Micron's GDDR5X memory. The 256-bit memory interface runs at 10Gb/sec., helping to drive 1.7x higher effective memory bandwidth than that delivered by regular GDDR5.
• Superb Craftsmanship. Increases in bandwidth and power efficiency allow the GTX 1080 to run at clock speeds never before possible -- over 1700 MHz -- while consuming only 180 watts of power. New asynchronous compute advances improve efficiency and gaming performance. And new GPU Boost™ 3 technology supports advanced overclocking functionality.
• Groundbreaking Gaming Technology. NVIDIA is changing the face of gaming from development to play to sharing. New NVIDIA VRWorks™ software features let game developers bring unprecedented immersiveness to gaming environments. NVIDIA's Ansel™ technology lets gamers share their gaming experiences and explore gaming worlds in new ways.

The question is whether this mention is like their previous mention of async compute on the maxwell cards or they actually do have the ability to take advantage of it now.

can't wait for the tests because all these claims need some actual demonstration. It seems they take the best case VR with simultaneous multiprojection and use those figures.

Ok... sorry if I am pesimistic, but nVIDIA as AMD didn't targeted the high end this time... nVIDIA targeted the Mid Range and AMD the mainstream tier.

Now... we need to wait until a 1080 appears and is compared against a Fury X and the 980 Ti (which is better than Titan X by even 20%).

Also... seems that nVIDIA is only releasing the big formats and not the Small form cards, to compete the Fury Nano...

But still, seems that 4K is out of reach to everyone for now. I know that the flaships will do that without problems.
And also... seems that nVIDIA did the way AMD did on the previous generation: only released the desktop cards and not the laptop chips. So we need to wait some time more before seeing them.

Anyways, I was expecting a launch of the 1060 Ti in order to cancel all AMD moves, however they didn't and they left a big opening in the budget market. Also... as I said again, AMD can drop the prices of the Fury Nano and fight against the 1070 despite being on disadvantage (a big one). On the other hand is great to see new cards and is great that nVIDIA finally starts the new generation of cards.

The official clocks of the GTX 1080 are listed as 1733 Mhz, but the demo that was shown on the Nvidia special event was actually running at a cool 2.1 Ghz. And that too on an air cooler! This means that the demo was actually running almost 23% higher than the official boost clock (which is already 40% higher than Maxwell by the way).

...NVIDIA’s new SLI HB bridge doubles the available transfer bandwidth compared to the NVIDIA Maxwell™ architecture. Delivering silky-smooth gameplay, it’s the best way to experience surround gaming—and it’s only compatible with the GeForce GTX 1080.

...Unfortunately NVIDIA has not yet disclosed detailed specs of GeForce GTX 1070. It is only said that it has 6.5 TFLOPs performance and that it’s faster than TITAN X. Assuming it has similar clocks to GTX 1080, then it should have around 2048 CUDA cores.

Introducing the GeForce GTX 1080. Gaming Perfected.


NVIDIA GeForce GTX 1080 Reference Pictured, Just 1 Power Connector

At its pre-Dreamhack launch event, we caught a glimpse of a GeForce GTX 1080 reference-design graphics card working. The card looks a lot better in the flesh than some of its early pictures, and in our opinion, looks better than even the NVTTM cooler NVIDIA used on some of its earlier generation graphics cards. It also features a solid-looking backplate.

There are two stunning attractions here - firstly, the GeForce GTX 1080 draws power from a single 8-pin PCIe power connector! This speaks volumes about its energy-efficiency. Secondly, it features a similar display connector layout as the previous generation, but the connectivity is revamped. It features three DisplayPort 1.4 (that's right, one point four) connectors, which supports insanely high resolutions; an HDMI 2.0 connector and a dual-link DVI port.

Pffft, "Irresponsible amounts of performance" and by the end 2016 you'll have a AAA title not able to hit 60FPS with all the bells and whistles turned on (and no not 16x AA) . . . . at 1080p.

 

[Aikouka]

I guess the question is... how well does it OC? The 980 Ti is a pretty decent card when it's OC'd, and that will definitely cut into the guesstimated 25% performance increase that the 1080 has over the 980 Ti.

I'll still most likely upgrade since I bought a 980 Ti recently with the plan to Step Up to the 1080. Given that I paid about the cost of the 1080 for the 980 Ti, I should pretty much have to pay for nothing but shipping. Although, thinking about it now... the lower power consumption (based upon the single power connector) might be rather welcome as my computer is in a smaller room, and when I play games, my thermometer, which is sitting on top of my case, goes from maybe... 69F to around 75-77F. In other words, my computer really heats up this room, and the 1080 may help with that while providing a similar experience.

 

[sontin]

In the marketing video they said "over 2GHz overclocking". And in the live demo the card run at 2112Mhz.

Yeah, but will you need the "Founder's Edition" card to hit high clocks like that? Remains to be seen I guess. I might be in at $600, but if I need to spend $700 on the binned cards to get a good OC, forget it - I'll wait for the 1080 Ti.

 

[therealnickdanger]

Am I reading all this correctly? Pascal is clocked ~33% higher (2GHz vs 1.5GHz) than Maxwell, but actually only ~25% faster? Even with fewer cores, isn't that a regression?

Compared with GTX980TI it's 1733 mhz against 1075 mhz boost clock, so 60% increase.
8,9 Tflop vs 6 Tflops. 50% increase in Gflops
ROP pixel rate: 110912 vs 105.776 MPix/s nearly no increase
Bandwidth : 320Gb/s vs 336 GB/s even decrease against 980Ti

This could lead to bigger gains in traditional AMD titles, as they are more compute heavy, but problems in ROP and bandwidth heavy titles.

 

[renderstate]

Sub-linear scaling is the norm.

 

[Shmee]

I am curious as to SLI scaling and technology, and mining performance.

 

[biostud]

Personally I think the Display Port 1.4 is a big thing, maybe monitors will skip 1.3 and move directly to 1.4.

this should support 4K 120Hz HDR

[positivedoppler]

Looks like a pretty nice card even with the $600 price tag. Feel bad for the old 980 Ti owner though which has been out to market for under a year and already severely obsolete. The 3X VR claim seems to be outrageous and I wonder what kind of measurement they're using but everything else is a stunning upgrade..just wow. For 180 watts...my PS is 1,000 watts... -_- AMD is going the low power route I was hoping Nvidia crank out something not so conservative...still...here's to hope it overclocks beyond 300 watts!

 

[xpea]

But Roy Taylor told us that NVIDIA wasn't going to provide good performance at mainstream price points. Did an AMD executive mislead people again ?

In the marketing video they said "over 2GHz overclocking". And in the live demo the card run at 2112Mhz.

3dMark leak claims 1.86ghz boost clocks on the ref 1080.

You can figure the % OC gains from that for a 2.1ghz boost.

980Ti and Titan X for example, boost 1.2ghz for the ref card. OC to 1.5ghz is a big %.
