Some leaked Nvidia Kepler info:
http://lenzfire.com/2012/02/entire-nvidia-kepler-series-specifications-price-release-date-43823/

Highlights:

Nvidia Kepler GTX690
750MHz Core clock
2×1.75 GB 4.5GHz GDDR5 Memory
2×1024 Stream Processors
2x448bit Bus Width
Priced at $999
Both AMD and Nvidia are following the same trend in maintaining the order of the series in GPUs. Like HD 7990, GTX 690 has a core clock lesser than GTX 680 and Bus width similar to GTX 670. Compared to AMD HD 7990′s price point of $ 849, GTX 690 is priced at $ 999. But comparing to the performance the GTX 690 can offer, HD 7990 is definitely over priced, and sure AMD has to reduce their prices drastically after the release of GTX 600 kepler series.

Nvidia Kepler GTX680
850MHz Core clock
2 GB 5.5GHz GDDR5 Memory
1024 Stream Processors
512bit Bus Width
Priced at $649
45% faster than HD 7970
Nvidia has a clear winner in its hands and that’s why they have commented that they had expected much more from AMD. But still we already know that AMD is preparing its revised GCN HD 8000 series graphic cards, which may be release in the latter half of this year.

Performance similar to GTX580



Looks like they are one-upping the 7970 on performance but more expensive, and still lagging on VRAM capacity for triple monitor support...lame. No mention of whether SLI is still needed for triple monitor either.

Continuing to watch and wait for the 7970 E6 6GB and hopefully a 680 Zotac with at least 4GB VRAM.

Then again maybe the leaked info is not real? Hopefully something official soon.

Update: some further research and posts on OCN seem to be of the opinion that the above article is fake specs... I sure hope so was hoping for at least 3GB VRAM and triple monitor support on the GTX 680.

Don't know if its fake info or not. To be sure, it could be something just to keep folks from buying AMD "while they wait"

I too have read that Kepler will be faster than comparable HD7xxx cards. However, not always by a lot. Rather, Kepler will show the big advantage on a handful of games optimized for Kepler architecture (particularly games with heavy PhysX), is the rumor.

Hopefully, prices will become more "sane" when Kepler hits the streets.

We'll see in a couple months

BTW, the most interesting rumor (to me) is that Kepler will NOT have "up-clocked" shaders.

For a few generations, Nvidia did better per shader than AMD partly because they ran their shaders twice as fast as the card base speed (faster than AMD shaders). Now the shaders are rumored to run at the card base speed. That alone could "slow down" FPS substantially per shader. We'll see.

I can't believe they're running prices like that. Obviously they feel that people will pay whatever for the next slightly faster card.

At that price I would hesitate to buy a 660Ti, even though traditionally the 670 is what I would go for.

Well, I'll buy when the prices are what I think they should be. My 570 is doing just fine right now. I could probably upgrade to a 580 for cheap once these are out.



The Jedi Master

And no word yet on their "surround gaming" on a single card?

Yeah exactly, all we can hope for is that this is fake specs and pricing as some say...

I was hoping the 680 would have at least 3GB VRAM and triple monitor "surround" on a single card, if Nvidia misses the Eyefinity boat again on this generation of cards, ATI will eat their lunch.

Hopefully NV will put out some official info soon, it's bad enough that they are 3 months behind ATI/AMD on the release but worse even that they don't put out specs so it leaves people open to fake stuff and conjecture.

Should drop the price of the 580 though.

Rumors are rumors..

look at the Bulldozer's Rumored Performance -> Actual Performance....

Seem like the "big" Kepler chip has "just taped out". So, one might expect the top card in late Summer to Fall 2012. Just about when HD8xxx might hit the market (or might not ).

GK110 Tapes Out

BTW, the rumor indicates Nvidia's first try at 28nm failed -- that's why they are late. Heck, AMD had a good, working 28nm design over a year ago and were just waiting for the TSMC 28nm manufacturing process to catch up. Some of those good features were "added" to the 40nm HD69xx cards while they waited (cards take 3 years to design/develop/produce -- so next year's cards have already been in the works for 2 years).

if only AMD can catch up to Intel....
