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.
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.
OpenGL ES is used for games on mobile devices such as smartphones. Newer versions support better graphics.
The fifth-generation wireless technology delivers higher speeds and lower latency than the previous, fourth-generation tech.
