Overclocking results were standard-fare for a GTX 1060 and only a few MHz higher than what we achieved on the Founders Edition. Certainly there's no speed binning or cherry picking going on with this SKU which more firmly cements the conclusion that there's no need to buy the more expensive STRIX OC variant when you can easily overclock the standard STRIX to the same levels.
Any variance between the two would be down to random silicon variation. The effective peak clock speed is just shy of 2.1GHz, a highly impressive number.
The ASUS averaged 14731 points in 3DMark compared to 14290 for the Founders Edition in its overclocked state. The combination of the extra few MHz and absence of thermal throttling explains that difference.
