There’s a new iPhone. Well, to be completely accurate there are two new iPhones. But the new iPhone 5S is Apple’s flagship phone and it’s the best iPhone you can buy. It looks exactly like how the iPhone 5 looked last year but with improved internals and guts that will make everything run even faster. Twice as fast, Apple says. Oh and it also has a fingerprint scanner.

Design

There’s nothing too different about the design of the new iPhone 5s compared to last year’s iPhone 5. The icon-less home button has a silver (or gold) ring around it to signify the 5s-exclusive fingerprint scanner but everything else is pretty much the same. Same unibody aluminum body. Same two-toned design. Same 4-inch display. All your cases for the iPhone 5 will work with the 5S.

One thing is new though. The iPhone 5s now has a new gold color option, along with the usual black and white (which is now weirdly called space gray and silver).

The Guts

Powering the iPhone 5s is Apple’s new A7 processor which is a 64-bit chip. It’s the first 64-bit chip in a smartphone and it’ll make the iPhone 5S two times faster than the iPhone 5 (and 40 times faster than the original iPhone). The 5s runs OpenGL ES 3.0 which makes the graphics performance in the 5s pretty gnarly too (that’s 56x faster than original iPhone, which yay, I guess?). The A7 chip has 3x general-purpose registers, 2x floating-point registers and over a billion transistors.

Along with the A7, Apple is using a “motion coprocessor” in the 5s called the M7. It continuously measures motion data with an accelerometer, gyroscope and compass support. It’s supposed to “enable a new generation of health and fitness apps” by letting apps use all that motion data without tapping into the A7.
