It’s finally time to see what this revolutionary new iPhone has in store for us.

At a glance, the 6s is the spitting image of its older sibling, but there's a lot more to it than meets the eye. Here's some of what's under the hood:

Improved Touch ID home button

5 MP FaceTime HD Camera

Retina HD Display with 3D Touch

Laid out side-by-side, there are few notable differences between the two—sans the new Rose Gold enclosure.

Upon closer inspection, the 6s is a hair larger than the 6 (138.3 x 67.1 x 7.1 mm vs. 138.1 x 67.0 x 6.9 mm), and it's stamped with a new model number: A1688.

The 6s has also packed on a bit of weight when compared to its older sibling, weighing in at 143 grams vs. the 6's 129 grams.
