Possible specifications of NVIDIA's GeForce 700 series which is assumed to be a Kepler refresh have been detailed by 3DCenter. The GeForce 700 Series would be a refresh of the 28nm Kepler GPUs just like the Fermi GeForce 500 series refresh bringing in enhanced performance through increased core count and higher clock frequencies.
NVIDIA Next Flagship GeForce - GK110 GTX 780
By 2013, NVIDIA would have finally enhanced the GK110 process through TSMC allowing for mass production of the chip allowing it to head towards the consumer market. Hence, the GK110 bearer of 7.1 Billion transistors and upto 2880 Cuda Cores with its full 15 SMX units would possibly enter as the flagship chip of the GeForce 700 series on which the GeForce GTX 780 and even the GeForce GTX 770 would be allegedly based. Although not with the full SMX set enabled, the GK110 would probably be a trimmed down version meaning we would only see 11-13 SMX units on the consumer level GPUs if NVIDIA wants to make them priced along the US $499 and $599 mark.
GK114 Headed towards the Performance Segment GTX 760 Ti
The successor to this generation GeForce 600 series flagship GK104 chip would arrive by the name of GK114 and could be fused on the GTX 760 Ti and even the GTX 760 parts which suggests their performance would end up being at par with current GTX 670 and GTX 680. Specifications would be deemed the same as GK104 though clock speeds would be improved, we are looking around the same core count of 1536 Cudas and a 256-bit memory interface on both cards.
GTX 750 Ti to Get Updated with GK116 Core
The GK106 would see its successor as the GK116 which is suggested to pump up the price to performance ratio much higher than its predecessors and would possibly arrive on the GTX 750 Ti and GTX 750 models. So NVIDIA without much development on their hands would gain a sizable performance increase over the GeForce 600 series with its GeForce 700 series. The best part is that we would finally get a better 192-bit memory interface on both cards with around 960 cores as opposed to 128-bit on current GTX 650 and GTX 650 Ti GPUs.
Rival AMD on its end would be prepping for the launch of Sea Islands 8000 series and they don't look that shabby either with an expected performance improvement of around 15-20% over the Southern Islands 7000 series cards. Both line of GPU's are looking really great for the consumer market delivering improved performance as the process matures over time. Those looking for the real deal better yet wait for the Maxwell and Volcanic Islands to arrive in 2014.
