The Pentium N3520 is an entry level quad core CPU based on the Bay Trail generation Atom CPU that is meant for inexpensive / budget laptops. In other words, it is less powerful than a Core i3 CPU. But it is faster than previous generation Atom CPUs. The integrated graphics is also very weak. Below is a link to some benchmarks of the Intel HD (Bay Trail) graphics core... it is not pretty... then again was not meant to play games except games from the Microsoft App store which are designed to run on tablets.
Below is a link to GTA 5 being played on a laptop with a 5th gen Core i3 and the Intel HD 5500 which is a lot more powerful than the Intel HD (Bay Trail) graphics core. Graphic settings are set to low and the resolution is 1280x768. The FPS counter is in the top left corner.
