First, the subject is different
1, the graphics card: is one of the most basic components of the personal computer, the purpose is to convert the display information required by the computer system to drive the display, and to provide the display line by line or interline scanning signals.
2, display chip: it is the main processing unit of the graphics card, so it is also known as the graphics processor.
Two, technology is different
1. Graphics card: The various 3D effects supported are determined by the performance of the display chip, and what kind of display chip roughly determines the grade and basic performance of the graphics card, such as NVIDIA's GT series and AMD's HD series.
2, display chip: the core technology used is hardware T& L (geometric conversion and light processing), cubic environment material mapping and vertex blending, texture compression and bump mapping, dual texture 4-pixel 256-bit rendering engine, etc.

Three, the role is different
1, graphics card: responsible for converting the display signal sent by the host to the display into a general electrical signal, so that the display can understand what the personal computer is doing.
2, display chip: the graphics card reduces the dependence on the CPU, and completes some of the work originally belonging to the CPU.
The graphics card is an overview, including the graphics card chip, graphics memory particles, output interface, cooling module, power supply phase... The graphics chip is the core of the graphics card. The two are not the same level of things, there is no way to compare, like \"your heart is different from your own\"?
