Re: The interesting bit...
Yeah, I was more interested in the new silicon too (because similar hardware efforts are in the pipeline from the likes of Qualcomm and probably Google too). These new phones are the first outing for Apple's in house GPU since they ended their relationship with Imagination Technologies. And their Image Signal Processor - let's not forget that the big stand out feature of Google's Pixel phone was cunning software treatment of the sensor data. There's some custom silicon for video motion tracking too. What makes this more interesting than the likes of Project Tango is that these iPhones will ship to interest developers.
