They did ok moving from the 5000 series to the 6000 series....

7990 would be easy, power consumption wouldn't be that much worse then the 6990 and GTX 590.

If true, the GTX 780 would be fearsome indeed.

We'll find out for certain soon.
I think what he meant is that they have to tackle the power problem first, with performance being the second priority. Whereas Nvidia has room to bloat their consumption in pursuit of performance.

Still no solid proof that this will bare the GTX 780 nomenclature. What of the 2880-core dies? Maybe this will be the GTX 760 ti or GTX 770

Awesome news but will it be voltage-unlocked?

Implementation of Green Light Program indicate that releases going forward 'may' be locked thumbsdownsmileyanim.gif

2304 - 1536 => 50% increase in shaders
312GB/s - 192 GB/s => 62.5% increase in Bandwidth.
1150 - 1058 => 8.5 increase in clock speeds.
GTX 680 => GTX 670
1536 -> 1344 => 5.7 % CFC (on average) thus 192 net about 40% increase.
From overclocking the memory
7430 => 6008 = 45% scaling (with my 670)
2304 => 1536 = will probably net 20% increase
312 GB/s => 192 GB/s = 28%
Clock differences => 4.5%
Total Difference = 52.5%
If a GTX 680 get 25 fps in a bandwidth hungry game the GTX 780 should get around ~ 38 fps in the same place drool.gif.

I trust your calculations but ~12 extra FPS?????? Sorry, but that's horrible if we think about it. 38FPS is still terrible and nowhere near the smoothness of a 60FPS.

I might end up buying a 780 but these improvements are still crappy. It shows how much they've got us by the balls.

Or maybe I'm just being greedy???

The article isn't short enough to quote all of it. Please trim the quote and add a Google Translate link or something similar to that.

I decided to stick this in the appropriate section, as it still is really a rumour. It's only a small article, so i'll post the whole thing translated.
Given the increased pressure from AMD, and Nvidia's own GreenLight (virtual nail in the coffin). Could it come sooner than we thought?

I tried to translate it a little bit better:
Quote:
There is new information about Nvidia's upcoming single-GPU flagship, the GeForce GTX 780. The revised Kepler chip named GK114 wil have more shader units which will work at higher clock frequencies.

In contrary to GK104 on the GTX 680, the GTX 780 will have 2304 instead of 1536 shader units. More shaders should give a decent boost to gaming performance but Nvidia also wants to expand the memory: 384 instead of 256-bit connected to 3GB GDDR5. Nvidia will also marginally increase the memory and GPU clock speeds of the new Kepler.

There are sources that say that the Nvidia GeForce GTX 780 will appear later this year. We think those are a little optimistic and we rather expect a start in the first quarter of 2013. The GTX 680 is not even a full year in business after all.

I'd like an extra 12 fps in Witcher 2 - maxed out thumb.gif

"If game is bandwidth hungry" Mean big resolution, Right?

So one GTX 780 go up 30 with Batman: Arkhamn City. Then fps go under 30 and i notice that.
38 fps is just fantastic 4320x2560 resolution. IF is not go under that wink.gif (I have for now 7950 CF)

I play most single game whit pad with really nice couch tongue.gif.
