The slide showed the performance comparison between GTX 580 and GTX 780, test bed included Core i7-3960X CPU, Windows 7 64-bit OS，297 series graphics driver, resolution of 2560*1600，AA/AF enabled. As the test result indicated, GTX 780 outperformed GTX 580 by a large margin, with performance increase ranging from 50%-100%.
Report: NVIDIA GK104 branding, specifications revealed:
http://vr-zone.com/articles/report-n...led/14589.htmlGK104 impressively doubles up on GF114's core count to 768 CUDA cores - although Kepler shaders will be different from Fermi counterparts. Single precision performance is rated at above 2 Teraflops, twice that of GTX 560 Ti and over 50% higher than GTX 580. GK104 will continue to feature a 256-bit memory interface, but with frame buffer doubled to 2GB presumably at higher clocks. With everything increasing, unfortunately so does power consumption, to a TDP of 225W. A GTX 660 Ti variant is also expected in the future.
http://en.expreview.com/2011/12/21/n...ted/19764.htmlGK100 features 1500 CUDA Cores, GDDR 5 memory with memory interface of 512-bit, the performance is close to the dual-core GeForce GTX 590, it’s scheduled to debut in Q2 2012. While GK104 features 1000 CUDA Cores, GDDR 5 memory with memory interface of 256-bit/384-bit as well as core/Shader frequency of over 1GHz, the performance is likely to be slightly higher than that of GeForce GTX 580, it’s expected to arrive in January or February 2012.
Rumour: NVIDIA GeForce GTX 680 to release in February

NVIDIA GK104 PCB Pictured
http://vr-zone.com/articles/nvidia-g...red/15095.htmlThe picture confirms everything discussed in the diagram leak article - from the overall length, unique stacked power connectors, the five phase VRM, 2x SLI connectors to the display outputs. The 2x DVI seem to be stacked like AMD's Radeon HD 5800 and 6900 graphics cards, constricting exhaust flow. In addition, HDMI and DisplayPort outputs are present. While it is difficult to tell from this angle, this particular PCB - most likely an engineering sample - appears to be sporting the 8-pin + 6-pin stacked power connector, as opposed to the previously leaked 2x6-pin stacked variant. It remains to be seen which configuration the final production boards will ship with.
As for the bits not shown by the drawings - a total of 8 memory chips are present, which all but confirms the heavily rumoured 256-bit memory interface. A total of 2GB GDDR5 memory is expected. At first glance, the die appears to be similar in size to Tahiti, perhaps a tad smaller. Unlike recent NVIDIA performance GPUs, GK104 sheds the headspreader.
GK104 is reported to release as GeForce GTX 670 Ti later this month.
