There are of course, more differences than one which warranted Huawei to make another phone. One, the screen size on the Honor 5X is 5.5-inches (with a full HD resolution). Other differences include the CPU, RAM, etc., as you shall read further.
The Honor 5X comes with the new Snapdragon 616 processor, an octa-core CPU @1.7GHz along with either 2GB or 3GB RAM. There’s 16GB of on-board space on the Honor 5X, but you can easily increase that with a microSD card.
Moving on, there’s a 13 mega-pixel camera on the rear (which sites above a fingerprint sensor that is claimed to unlock your phone in just 0.4s), and a 5 mega-pixel one on the front. A 3000mAh battery powers the phone, which looks like a decent package overall with a 999 Yuan ($157) price tag for the base 2GB RAM version, while the 3GB RAM Honor 5X is 1399 Yuan ($220).
