Monsters from Asia: vivo X5Max, the world's thinnest production phone

Surely, that leaves little room for anything resembling powerful internals, right? Not quite, for vivo has fitted within an octa-core Qualcomm Snapdragon 615, 2GB of RAM, a 13-megapixel rear camera, a 5-megapixel selfie snapper, a 2,000 mAh battery, and even a dedicated Yamaha YSS-205X chip to handle audio output (vivo is well loved among audiophiles). The device runs on Android 4.4.4 KitKat, with the company's proprietary Funtouch OS 2.0 skin on top.
So how much for the razor-thin vivo X5Max?
