According to earlier rumors, the Nvidia Geforce GTX 1060 is based on Pascal GP106 GPU and should feature 10 SMs with 1280 CUDA cores, 80 TMUs and 48 ROPs. The GTX 1060 could be based on two ASICs, GP106-400-A1 and GP106-300-A1 and come with 3GB and 6GB of GDDR5 memory paired up with a 192-bit memory interface. The GPU should end up with a GPU Boost clock of 1.7GHz while memory should be clocked at 2000MHz (8.0GHz effective), for a total memory bandwidth of 192GB/s. 

Newest rumors, caught by both Techpowerup.com and spotted in a leaked set of slides from Videocardz.com, suggest that the GTX 1060 could be officially launched in July, precisely July 7th, with market availability expected a week after, on July 14th.  

According to what appears to be Nvidia official slides, the GTX 1060 will offer "the power of GTX 980 for every gamer", which also suggest that it will be aggressively priced and according to the performance and efficiency slide, it targets AMD's newest Radeon RX 480 and should be faster in both gaming and VR and be significantly more power efficient, especially with the 120W TDP. Of course, bear in mind that this is Nvidia slide and since it starts from 0.8 we can't get a clear picture of how much faster or power efficiency will the GTX 1060 actually be.

The earlier leaked picture showed the GTX 1060 Founders Edition and it is still not clear if Nvidia AIC partners will be making custom GTX 1060 graphics cards from day one.

It was pretty clear that Nvidia won't be sitting idly as AMD gets a tight grip in the mainstream market, and while RX 480 is selling quite well, upcoming Nvidia GTX 1060 will definitely ruin its celebration.
