Here's a neat GTX 1070 sample. Chip and PCB dated in the middle of March, 2016. Rear shroud and fan housing are unfinished raw aluminum, forward shroud has the rough black stippled finish used on the Titan X Maxwell. All portions of the cooler shroud are dated March 16, 2016, the heatsink assembly is dated individually with what appears to be either April 17th of April 11th, 2016. The heatsink is otherwise identical to the retail version.
Performs exactly as you'd expect any 1070 to perform. Some quick "all sliders maxed" tweaking yielded 2126MHz max boost, 2085MHz average boost, and 2238MHz GDDR5. The firmware is a later build. Presumably this card sat around for awhile testing firmware builds before being taken home or dumped at a recycler.
