The very first pictures of what is believed to be next-generation Nvidia GeForce code-named "Kepler" graphics cards along with a scheme of printed circuit board have surfaced on the web (at Chiphell and Expreview web-sites). The GeForce Kepler GK104 is clearly projected to be a high-end solution, the card itself is evidently rather huge.

Nvidia GeForce "Kepler" GK104 graphics card looks exactly like a high-end adapter: it has very tricky 5-phase power supply system with very unusual set of PCIe power connectors. According to some media sources, the external power supply system may include two 6-pin and an 8-pin PCIe power plugs, which means that the card will have rather high power consumption. In addition, the board has two MIO connectors, which are found only on high-end products, to provide three-way or four-way multi-GPU SLI configurations. The new adapter has DisplayPort, DVI and HDMI display connectors.

The card, which is allegedly powered by Kepler graphics processing unit (GPU), carries eight GDDR5 memory chips on its front side. If the card has another eight chips on the back side, then it has 512-bit memory bus, if not, then it sports 256-bit memory bus, which is something strange.

The GK104 chip does not seem to be too huge and therefore too expensive. Some believe that Nvidia is also preparing code-named GK100 chip, which will have even higher graphics and compute performance. Exact specifications of the GK104 are unknown.

Nvidia has very high expectations for its Kepler generation of graphics processing units (GPUs). The company claims that it had signed contracts to supply mobile versions of GeForce “Kepler” chips with every single PC OEM in the world. In fact, Nvidia says Kepler is the best graphics processor ever designed by the company. Unfortunately for Nvidia, yields of chips made using 28nm process technology at TSMC, including Kepler, are lower than the company originally anticipated and therefore their costs are high and Nvidia's chief executive recently complained that the company cannot get enough wafers.

Kepler is Nvidia's next-generation graphics processor architecture that is projected to bring considerable performance improvements and will likely make the GPU more flexible in terms of programmability, which will speed up development of applications that take advantage of GPGPU (general purpose processing on GPU) technologies. Some of the technologies that Nvidia promised to introduce in Kepler and Maxwell (the architecture that will succeed Kepler) include virtual memory space (which will allow CPUs and GPUs to use the "unified" virtual memory), pre-emption, enhance the ability of GPU to autonomously process the data without the help of CPU and so on. Entry-level chips may not get all the features that Kepler architecture will have to often.

Nvidia did not comment on the news-story.

100 Bitcoins, mined with AMD's GPUs

"This is the nvidia high end GPU, The rest is all lies to save face"

I hope nvidia has 2 cards coming other than this or that this is an 512 bit card, otherwise its a win for AMD.

Definitely can't see how this is their high-end card. 256-bit memory bus doesn't compute for a high-end card. Unless NV decoupled the memory controller in a fashion similar to AMD's and this is a 384- or 512-bit card.

This is probably just a GTX670Ti style card. If this is their high-end GTX680 card, how are they going to handily beat a GTX580 with only a 256-bit bus?

GK104-400(680 or 670 Ti) - 950 MHz / 1.9 GHz ~225 W TDP
GK104-335(670 or 660 Ti) - 1000 MHz / 2 GHz ~210 W TDP

Just wanted to post this somewhere.

It seems to be all over the place

Certain models have hot clock removed so they can raise overall clock

Possible models:
GK107(GF108 Rebadged)

GK104 is GF110 refined. If it was on 40 nm it would most likely have been called GF120.

I don't really trust the removal of hot clocks.

GK112 => 800 MHz / 1600 MHz / 5.5 Gbps
GK104 => 950-1000 MHz / 1900-2000 MHz/ 5.8 Gbps
GK106 => x MHz/ (x * 2) MHz / 4.8 Gbps

And the cheaper version "335" has more expesive chips clocked @8Gbps? This seems reasonable fud.

I have been reading that there will be 3 cards that NVidia will be releasing. Does anyone know if the 680/780 is one of them? is there going to be 685/785 how there was in the 2XX series? Anyone know anything?

Is a total nonsense judging by the introductory prices only. 500USD for the top end envydia card ... it wont happen anytime soon. Except if we shouldnt expect ultimate failing to deliver Kepler line of GPUs

These are probably bigger chips than Tahiti and as we can see need pretty insane power supply for GK104. And Expected GK110 could be only even more power hungry monster. And all these and insanely huge cooling are expensive. Way more than 500USD could describe.

If Nvidia beat AMD GPU with lower power consumption then I'm impressed but looking again to that picture looks like another power hungry card again just to beat AMD GPU. Some say it is 375W card. 5 phase power system? Not a power saving feature I know specially for mainstream level card.

5 phase power system is similar to HD7950/7970.

GTX670Ti may as well be GK104, in which case it is a replacement for a GTX560Ti. That can easily compete with HD7950 and not be NV's high-end.

But it also could mean that card we see above can have 2 versions:

256-bit GTX670Ti
512-bit GTX680 Ti with 8 more chips on the back (and that 6+6 pin connector is replaced with 6+8).

Can't wait. Finally some competition.

Looks like there's another card, distinct from GK104, which is 1/2 inch longer, etc..:

I do not think it will be 512-bit because GK104 is a bit smaller than GF114 (see above link for more).

Never mind - some are now saying that the "alleged" GK100/110 diagram in the above link is fake..

OMG! I just realized you are the Fox behind VoodooPower Ratings.

Wow, job well done. Extremely useful and rather accurate chart to show to people who don't want to look at 100 benches to see how fast their card is.

2 Thumbs Up.

Xbitlabs is attracting some knowledgeable techies

Thank you!!! It's a lot of work and I plan on doing another list for mobile GPUs. Xbitlabs is always checked as a really useful source. Thanks again!!

Blah blah blah. the card will be out soon and put to rest all the ridiculous speculation.

Yeah...once the gk104 comes out, we can start making ridiculous speculations about the gk110. One thing I know for sure is 1) Nvidia is going to blame tsmc for any delays & 2) Kepler is worth the wait (we will at least see some price drops).

Developers still have not made any game that resembles the Unigine Heaven DX11 benchmark. If everyone stopped buying DX11 cards for 6 months, we would start seeing AMD and Nvidia invest more $ on DX11 games.

Praise .... first pictures of real PCB. And that was good.

It's a grotesque monster card. It has FIVE rails to GPU PSU alone ntm at least one for front side memory. And the TDP is ...?? 260W judging by the hopefully 90% eff psu.

As long as the performance is amazing, a lot of enthusiasts could care less if it's a 300W card. I think people who complain that a high-end card is 250-300W should stick to mid-range line-up. HD7870 offers plenty of performance for 1080P and even with a 25% overclock is a ~200W card.

I think the high-end should 250W+ and offer maximum performance for a single GPU. I am not sure it's a problem for people dropping $500-650 on GPUs to care if it's a 250 or a 300W card.
1 3 [Posted by: BestJinjo  | Date: 03/05/12 07:12:38 PM]

I have a feeling that AMD has something up their sleeve. I'm not talking about a next generation part. What I'm talking about is something like an HD 7980. Even though AMD denied that they had a Tahiti GPU with 2304 cores, I think they lied so that they wouldn't butcher their HD 7970 sales. This of course is me just speculating.

I wouldn't be surprised if the Tahiti lineup got a pretty substantial performance boost with more mature drivers; yet, even with driver improvements, I don't see the 7970 beating a high end Kepler GPU. I hope that AMD realizes that consumers prefer 300W single GPUs instead of 300W+ dual GPUs (for reasons relating to stability).

I am an Nvidia user, But you are wrong AMD is already beating Kepler! Why you might ask?
Cause WE ARE STILL FREAKING WAITING NVIDIA, come onnnnnnnnnnnn hurry up and get something out. lol

HD7990 is delayed for a quarter or even 2.

There are rumors of a faster card from AMD:
