What is an integrated video card

Integrated graphics cards generally do not have video memory, using the system equipped with integrated graphics motherboard part of the main memory as video memory, the specific number is generally based on the need for automatic dynamic adjustment of the system. Obviously, if the use of integrated graphics to run a large number of memory-intensive programs, the impact on the entire system will be more obvious, in addition to the frequency of the system memory is usually much lower than the video memory of the independent graphics, so the integrated graphics performance than the independent video card less. Motherboards that use a chipset that integrates the graphics card do not have to use an integrated graphics card, and the motherboard can completely shield the integrated video card, which is rarely done for cost reasons.

In addition, some integrated graphics chipsets can also support separate video slots, such as Intel's G-Series chipsets, while others no longer support specialized video slots, such as Intel's GL series chipset.

Integrated graphics, by the motherboard North Bridge chip integrated display card chip board called the integrated Motherboard, the North Bridge integrated display card chip for the core of integrated graphics, the core and video memory composed of integrated graphics card. Integrated video card is divided into independent video memory integrated graphics, memory-divided integrated graphics, hybrid integrated graphics.

Independent video Memory integrated graphics card is on the motherboard has a separate memory chip, do not need system RAM, independent operation. Memory partition integrated graphics card, from the host system memory divided part of memory as video memory for integrated graphics calls, which is often seen in the integration of the graphics machine why the system memory and nominal discrepancy, less, is this truth. A hybrid integrated video card is used both for independent memory on the motherboard and for use with video graphics, such as AMD's 780G chipset.

Advantages and Disadvantages

In simple terms, the standalone video card can be upgraded, that is to buy the independent graphics with a sense of the mainstream of the game, you can go to buy a more high-end, and integrated video card is unable to upgrade, when the feeling of playing the game is very card, there is no way to replace the integrated graphics, this is a general statement.

The difference is that the performance of the independent graphics is very powerful, there are many integrated graphics not the most basic thing is the radiator, integrated graphics in the processing of large 3D games, the high energy consumption, and the independent video card has a radiator, you can play its performance, or even overclocking, and integrated video card is not a radiator, Because the integrated graphics card is integrated in the computer motherboard, when processing the same large 3D game, its heat reached a certain temperature, there will be a lot of things. This is the most basic difference, detailed is their memory, memory width, stream processor, using the GPU chipset, display frequency, core frequency, etc. are different, relative to the independent graphics for the game or high-definition 3D rendering, such as some film and video animation game production has a greater space to play, The integrated video card does not achieve the level of independent graphics.
