Hot Hardware published a review on the Galaxy S7 Vs iPhone 6S Performance Showdown Shows Samsung Has The Upper-Hand

A quote from the article:

To look at Samsung's new Galaxy S7 and Galaxy S7 Edge, on the surface, you might might think it to be a modest uplift of features, bells and whistles, and perhaps just a light rebuffing of the phone's design language. But beauty, as they say, is skin deep and one of the primary new features of the US-targeted Samsung Galaxy S7 is its underlying power plant--Qualcomm's hot off the fab line Snapdragon 820 system-on-a-chip (SoC).

The Snapdragon 820 has only made a sneak-peek preview to this point, taking residence in a phone from Letv back at CES 2016 in January, so the 14nm Samsung fab'ed chip has been a rarity of sorts until the launch of the Samsung Galaxy S7. As such, we were eager to see what the new Snapdragon could do when GS7 samples arrived, and of course how it stacks up versus Apple's A9 power plant in the iPhone 6S Plus.
