Heres one phone that didnt leak on the Asus e-shop: the Zenfone 4 Pro. Good thing GFXBench covered all its specs in detail! The base Zenfone 4 is expected to cost 500 with a Snapdragon 630 chipset, so what could a Pro model offer?
A Snapdragon 835 chipset, for starters. The Adreno 540 GPU is going to fly on the 1080p resolution of the 5.5 screen. Having 6GB of RAM will help with the more demanding games and apps as well (storage, however, is unchanged from the base model 64GB).
There will be a dual camera on the back that shoots 12MP photos. An earlier leak suggested 2x optical zoom, so this could be an upgraded camera module compared to the base model. The camera will shoot 2160p videos (duh) while the front 8MP camera will go almost as high (3,280 x 1,846px clips, claims GFXBench).

Unlike the regular Zenfone 4, the Pro seems to be a single-SIM device (a microSD slot is all but certain). Also, the phone will run Android 7.1 Nougat skinned with ZenUI and should be unveiled this week.
The Asus Zenfone 4 Pro was set to cost $650, but the same rumor claimed the regular Zenfone 4 will be $400 (the 500 figure comes from the Asus e-shop site). Prices for the Taiwanese market put the Pro model at just over 70% more expensive than the non-Pro. Whichever way you look at it, Pro isnt a synonym for cheap.
