What nVidia did was change the branding so that the labels are attached to chips one tier higher than they used to be. The 1060 has slightly higher power consumption and price than the 970M did. It's a higher end chip, with the 1050 being the replacement for the mid-range 960M.
If you ignore the branding then there's little change in desktop-equivalency.
The design change has bought a similar jump in performance to previous ones but the slightly higher peak power consumption means that Pascal isn't great news for laptop and other restricted cooling gaming systems.
Although the improved idle power consumption is nice.
