Graphics full display interface card(Video card,Graphics card), is one of the most basic configuration computer. Graphics as an important part of the computer mainframe, undertake the task of the graphics output, for people engaged in the professional graphic design graphics card is very important. Civil and military graphics graphics chip suppliers mainly include AMD and Nvidia.
The graphics card classification #
1.Core Graphics
Intel Core Graphics is a next-generation graphics processing core product, and in the past different graphics design, Intel, with its advanced technology in the manufacturing process and the new processor architecture design, integrated graphics core with the processing core on the same piece of substrate to form a complete processor. Intelligent processor architecture designed to integrate this greatly reduced the turnaround time for data processing core, graphics core, memory, and between memory controller, effectively enhance the processing performance and significantly reduce overall power consumption chipset helps reduce the core components the size of the notebook, one machine and other products designed to provide a greater choice.
Core Graphics advantages: low power consumption is the main advantage of the graphics core, due to downsizing and integration of the new design, the overall energy consumption of core graphics control more excellent, efficient processing performance significantly shorten the operation time, further reduce the energy consumption of the system platform. High performance is its main advantage: the core graphics technology has many advantages that can bring plenty of graphics processing power, progress compared to the previous generation of its performance is very obvious. Core graphics support DX10 / DX11, SM4.0, OpenGL2.0, as well as Full HD Full HD MPEG2 / H.264 / VC-1 format decoding technology, will soon join the performance can be significantly improved and more dynamic adjustment of Core Graphics processing capacity, so that it fully meets the needs of users in general.
Core graphics Disadvantages: Configuration CPU core graphics usually the price is not high, while the low-end nuclear significant not do the big game.
2.Integrated graphics
Integrated graphics is the graphics chip, memory and related circuitry are integrated on the motherboard, with its blend of components; display a separate graphics chip, but most are integrated in the motherboard Northbridge chip; some motherboard integrated graphics are separately installed memory on the motherboard, but its smaller capacity, display and integrated graphics processing performance is relatively weak, you can not upgrade the graphics hardware, but you can adjust the frequency by CMOS or brush into the new BIOS file for software upgrade to tap the potential of graphics chips.
Advantages of integrated graphics: low power consumption, heat a small, part of the performance of integrated graphics can already comparable to entry-level graphics card, so do not spend the extra money to buy a separate graphics card.
Disadvantages of integrated graphics: the relative performance is slightly lower, and the curing on the motherboard or CPU, itself can not be replaced, if necessary change, you can only change the motherboard.
3.Discrete graphics
Refers to the discrete graphics display chip, memory and related circuitry alone do a circuit board, but as a self-contained independent board exists, it will occupy the motherboard expansion slots (ISA, PCI, AGP, or PCI- E).
Discrete graphics advantages: a separate memory is installed, generally do not take up system memory, integrated graphics are more technically much more advanced, but certainly not worse than the performance of integrated graphics, easy to upgrade the graphics hardware.
Discrete graphics Disadvantages: System power has been increased, the heat is also large, extra spending money to buy cards at the same time (especially laptops) take up more space.
Model #
The company's main brand ATI Radeon (radium Long) series, the model by 7000,8000,9000, X series and then HD2000,3000 series Radeon HD 4000,5000,6000,7000 series.
The company's main brand nVIDIA GeForce (GeForce) series, the models from the early GeForce 256.GeForce2, GeForce3, GeForce4 to GeForceFX, then GeForce6 series, Geforce7 series, GeForce8 series, GeForce9 series and then to the recent GT200,300,400 , 500, 600 series.
Capacity #
Other parameters of the same capacity the better case, but not only noticed when comparing the memory card (js will be a lot of low-performance core with a large memory as a selling point). For example, the 9600GT 384M 512M is far stronger than the 9600GSO, because there is a gap between the core and memory bandwidth. When you select the graphics card memory capacity is only one reference, core and bandwidth and other factors are more important, these decisions take precedence over performance graphics memory capacity. But the necessary memory capacity is necessary because in the case of high-resolution high antialiasing may appear insufficient memory. Current market graphics card memory capacity ranging from 256MB-4GB.
Note #
With the development of chip technology display, showing more and more transistors inside the chip, increasingly high degree of integration, such an outcome would cause the chip's heat becomes larger, so the heat issue has become more prominent.
If the quality of the graphics card cooling fan is not satisfactory, you need to replace the fan. When buying a new graphics card fan, the best graphics card to bring, buy the right graphics card fan.
Mostly due to the use of spring clips or fan screws, so we can easily use a screwdriver and tweezers to remove it, and unplug the power connector connected. When replacing the original first-chip thermal grease to clean up, and then coated with thermal grease, the new fan installed – under them as they are fixed, plug in the power adapter can be.
Graphics using heat pipe cooling, due to its footprint than using big fan, so when the installation of such cards to pay special attention. Another graphics memory also need heat, we can use the existing self-adhesive grease particles fixed heatsink paste on it.

Install the appropriate drivers #
It is necessary, good graphics card installed driver will not greatly reduce the graphics performance.
