This model debuted in April 2015 so little more then year ago. It was middle segment device and it still works quite smooth but it's more due to OS then hardware.
Snapdragon 400 (quad-core 4 @1.2GHz), 1GB of RAM and 8GB of internal storage gives good performance even now. 5-inch screen with 720p resolution and 2500mAh battery for its actual price is a good combo.
