ASUS launched two models of the ZenFone 2 in the US: an entry-level variant with 16GB storage and 2GB RAM for $199, and a higher-storage model with 64GB storage and 4GB RAM for $299. The Taiwanese manufacturer has now made available a third version for $229 that offers 4GB RAM with 16GB storage.
Other specs are the same as the variant that retails for $199, which include a 5.5-inch Full HD IPS display with Gorilla Glass 3, 1.8GHz quad-core Intel Atom Z3560 SoC, 13MP camera at the back, 5MP front shooter, microSD slot, LTE connectivity, and a 3,000mAh battery. On the software front, you get Android 5.1 out of the box.
The major difference with the $299 version is the Intel Atom Z3580 SoC, which is clocked at 2.3GHz. If you're not keen on shelling out the $100 for higher storage and RAM, then the $229 model is an ideal alternative considering the device comes with a microSD slot.
