Chiphell and PCOnline have posted new (as in different from the old rumored specs) for the upcoming GTX 680. They also provided a picture of the GTX 680, which you can see below. The new specs differ from the old ones in the following ways. 1,536 CUDA cores instead of 1,024, 1,006MHz core clock instead of 850mHz, 6MHz GDDR5 memory instead of 5.5GHz and a 256-bit a memory bus instead of a 512-bit memory bus. So the new specs say that the card has more cores at a faster speed but the memory bus has been cut in half. I would be very surprised if the GTX 680 has a 256-bit bus when the GTX 580 had a 384-bit bus.

however some results don't match up with earlier ones, stating 40% faster in bf3 compared to 7970. a more recent one shows the difference at only 2.2 fps...
i'm getting very impatient to see real benchmarks from real review websites

I believe Nvidia did this because they noticed that their previously "mid-range" chip (gk 104) could beat out the 7970. So Nvidia wanted to save a buck and release a cheaper to manufacture card as well as have it low power consumption while beating out the 7970... now lets hope Nvidia prices the card well to beat that aspect out too.
