PCB board graphics card is a circuit board , it put its discrete graphics and integrated graphics on the distinction between integrated graphics chip is displayed , memory and related circuitry are doing on the motherboard, and the motherboard integration ; integrated graphics there are separate graphics chip , but most are integrated in the motherboard Northbridge chip ; some motherboard integrated graphics motherboard also separately installed memory, but its smaller capacity , display and integrated graphics processing performance is relatively weak , graphics hardware can not be upgraded , but you can adjust the frequency by CMOS or brush into the new BIOS file for software upgrades to tap the potential of graphics chips ; advantages of low power consumption and integrated graphics , heat a small , part of the performance of integrated graphics can have comparable entry-level graphics card , so do not spend extra money to buy cards .
Refers to the discrete graphics display chip , memory and related circuitry alone do a circuit board, and as a self-contained independent board exists, it takes up the motherboard expansion slots (ISA, PCI, AGP , or PCI- . E graphics card installed memory alone , generally do not take up system memory , integrated graphics are more technically much more advanced than the integrated graphics can get a better display and performance graphics hardware upgrades easily ; drawback is the system Power consumption has increased, the heat is also large, extra spending money to buy cards . discrete graphics card into independent existence , need to plug in the corresponding connector on the motherboard and graphics card with separate memory, do not take up system memory and technical leader in integrated graphics, can provide a better display and operating performance.
