1.Has integrated graphics
With integrated graphics you don’t need to buy a separate graphics card.
A 32-bit operating system can only support up to 4GB of RAM. 64-bit allows more than 4GB, giving increased performance. It also allows you to run 64-bit apps.
The graphics processing unit (GPU) has a higher clock speed.
Small semiconductors provide better performance and reduced power consumption. Chipsets with a higher number of transistors, semiconductor components of electronic devices, offer more computational power. A small form factor allows more transistors to fit on a chip, therefore increasing its performance.
DirectX is used in games, with newer versions supporting better graphics.
When the GPU is running below its limitations, it can boost to a higher clock speed in order to give increased performance.
