What is a GPU (graphics processor)?

A GPU is the chip that draws images and animations on your phone screen.

A GPU (graphics processor) is the part of a phone's chipset dedicated to rendering everything you see on screen, from the system interface to photos, videos, and games. It works with the main processor to speed up complex graphical tasks.

In daily use, the GPU determines how well games run, how smoothly you scroll between apps, and how good video playback looks. The stronger it is, the fewer stutters and delays you get, especially in heavy games or on a high-refresh-rate screen.

When buying, look for a GPU that supports screen refresh rates like 60, 90, or 120 Hz and modern graphics features. A mid-range GPU is enough for casual gaming, while a higher tier is better for serious gamers.
