Apple sent techheads swooning today when it officially announced two new iPhones: the iPhone 5C and the iPhone 5S.

Though it's available in new colors (silver, gold and "space gray"), the 5S doesn't look that different from the current iPhone 5—but is very different on the inside. (And will have a $199-$399 price tag when it goes on sale September 20.

NBC News reports:

This phone has had a massive overhaul inside the case, despite its resemblance to its predecessor. It runs the powerful A7 chipset, and runs 64-bit software, for all you nerds out there. It's not only twice as fast as the existing iPhone 5, but it's 40 times faster than the original iPhone, released in 2007.

The other new under-the-hood feature is an M7 chip, a "motion coprocessor" that accesses sensors without waking up main chipset. This will mean more efficient exercise apps and other active/location services.

The 8-megapixel camera has been redesigned with larger optics and a larger sensor. As Schiller says, "bigger pixels make a better picture," so the megapixel race takes a back seat. (Says Apple, but it rings true.) The "True Tone" flash adapts to lighting conditions better, and provides more natural light.

The camera's burst mode gives you 10 frames per second, if you want to get GIF crazy. It selects the best of the 10 in realtime. In video mode, there's a 120-frame-per-second slow-mo mode, and you can even toggle back and forth between slow mo and regular 30-fps shooting within a video.

What's got everyone talking is the 5S' new integrated fingerprint scanner, the Touch ID. It'll allow you to log into your phone with using a password and buy music on iTunes with a touch of your finger. Rumors that it will also devour your soul were not addressed.

The iPhone 5C (right) is basically the 5S's ghetto cousin: Coming in five Day-Glo colors, it'll retail for just $99 and is "unapologetically plastic," according to designer Jony Ive.

Ooh, girl, that thing's a little too Party City for us.
