ASUS Zenphone 4, 5, and 6
With the announcement of the new Zenphone trio (Zenphone 4, 5, 6) Asus is clearly targeting 3 different screen size markets. The Zenphone 4 comes with a 4 inch screen and a 1.2GHz dual core processor with 512 MB of RAM. The Zenphone 5 on the other hand packs a 5 inch IPS screen powered by a faster 2GHz dual core Intel Atom processor with 1 GB of RAM. The same processor is found in the Zenphone 6 phablet, but with either 1 or 2 GB of RAM and the screen size is bigger, packing a big 6 inch IPS display.
