CategoriesTechnology & Computing

dGPU stands for Discrete graphics processing unit, a computer hardware abbreviation.

Separate graphics processor with its own dedicated video memory, either on a plug-in graphics card or as a separate chip on a laptop's motherboard. It is needed for demanding games, 3D rendering and most AI work.

Example: Gaming laptops pair the iGPU with a dGPU and switch to it automatically when a game starts.

Usage notes

Also called dedicated graphics. Nvidia, AMD and Intel (with its Arc line, launched in 2022) are the main makers of consumer dGPUs. In laptops, a "MUX switch" lets the dGPU drive the display directly, bypassing the iGPU for higher frame rates. A dGPU can draw 100 to 600 watts at full load, far more than an iGPU.
