Max-Q technology is an energy-efficient modus for use in laptops fitted with this a compatible product. It makes them more energy efficient as well as more silent. Thus far there has only been Max-Q version of the GeForce GTX 1060, 1070 and 1080.
However as it turns out, the GTX 1050 and 1050 Ti are also arriving in the near future, this page for the Linux driver clearly shows and reveals that. Don't expect big announcements about it though. NotebookCheck, who spotted this entry, mentions that the Max-Q cards would be 10 to 15 percent slower compared to the regular version, based on experiences with previously released Max-Q versions. They also mention that the TDP should be between 34 and 46 watts.
That means these units could quite easily be used in very thin laptops and notebooks. The pending Lenovo Yoga 720S should be equipped with a 1050 Ti Max-Q.
