Despite the fact that the Mega 6.3 is running what many would assume "mid-range" specifications, it doesn't feel like a mid-range device. With its 1.7GHz dual-core Qualcomm Snapdragon 400 processor, 16GB of built-in storage, 1.5GB of RAM, you can do just about anything you want to do.
On the Quadrant benchmark, the Mega scored 8,203, easily topping the 5,607 smartphone average. The Samsung Galaxy Note II and its 1.6-GHz quad-core Exynos CPU managed a score of 6,036 while the Moto X's 1.7-GHz Qualcomm Snapdragon S4 CPU achieved 8,864.
For graphics performance, the Mega scored 5,300 on 3DMark, far below the 8,502 average.
Its scores in synthetic benchmarks weren't groundbreaking but were mediocre, at best. It tied the Galaxy Note II in many benchmarks, but was blown away by devices carrying Snapdragon 600 chips in practically every category.
The Mega is fairly smooth and quick for day to day use, switching between apps, and returning home. But certain elements of TouchWiz manage to bog the Snapdragon 400 down quite often, like scrolling through pages in the app drawer or switching to the Widgets tab.
