Graphic Card Buying Guide for shopwiki

The Graphic Card Buying Guide welcomes you to go through it and get an overall idea before making a purchase. Getting amazing deal is possible once you finishing comparing the costs of various top brand graphic cards at our website.

How do you think pictures are rendered on the display screen or monitor of the computer? Graphic card also known as graphic adapter, video card, and video adapter is the one which is responsible for that. It is a computer hardware piece installed inside the motherboard of the computer as an expansion slot. There are more types of graphic cards available now which differ from each other some or the other way. Hence choosing one can be really a challenging job.  

Graphic card types

The importance of graphic cards is well known by graphic artists and designers as they know how processing of pictures can bring down the speed of computers. Even though most of the video cards come these days in the PCIe format they are also available in the AGP and PCI old format. ACP or Accelerated Graphics Port is still famous as current computer users have got these slots in-built on to their computer motherboards. But new computers now-a-days have Peripheral Component Interconnect or PCI-express. This is so because it provides a wider data transfer scope to and fro the main memory and graphics card.

Certain CAD or computer aided design and high-end gaming systems have card slots that can accommodate one or more graphic cards. This enables you to achieve quick video performance.

Graphic Cards for different purposes

Not all graphic cards are meant for the same purpose as they differ from each other according to the purpose. For instance, beginner level graphic cards are most often used in desktop and business graphic functions, while the affordable, mid range types are used for web surfing, digital photography, light gaming, and so on. For 3D gaming and imaging purposes performance graphic cards are used. The games that need the best image quality and resolution make use of the graphic cards for enthusiasts.

Accelerated Graphics

Graphic card of olden days did not have much memory as their main purpose was to only display pictures or images. But today’s scenario is completely different especially after the boom of the 3D gaming. Fog effect, bump mapping, and textures lighting effects are some of the in-built instruction logic used by today’s graphic cards for processing the graphics so that it results in quick image display on the computer screen avoiding drop in the frame rate. 

The in built video memory of graphic cards can be in the range of 128MB – 512MB. The memory know as double data rate or DDR memory can transfer data two times more than the traditional memory’s speed. 

Anti- Aliasing

Anti-Aliasing is a new technology which is very different from the efficiency and speed of graphics as it results in smoothing the computer’s jagged sprites edges using color blending. Since the pixels on the monitors have rectangular shape diagonal lines cannot be drawn without appearing crooked. Even though this technology cannot avoid it, it is capable of tricking the viewers by making the pictures appear very visually pleasing and smooth.

Memory Bandwidth

The rate with which data is transferred to and fro the graphics memory and GPU or graphical processing unit is known as the memory bandwidth. For many years this was a major bottle neck. But it is no more a problem as the latest graphic card types come with high speed, memory solutions. The retrieval of textures and data from graphics memory increases when the graphics card with higher memory bandwidth is used. No wonder, this is one of the prime factors determining the choice of graphic cards.

Factors determining the graphic card speed measurement

You will find the graphic card speed measurement complicated than the measurement of speed of a hard disk, RAM, or CPU. Various factors come into play when determining the speed of the graphics card especially when performing certain errands. Even the hardware of the graphic card can have an impact on its speed.

Pixel pipelines in graphics card actually have a significant impact on the picture rendering speed. The more the pixel pipelines the more quickly the images are rendered.

Memory Clock Speed is very similar to the speed of the core clock; here it is the speed of the graphics card memory. This is vital to the application of memory textures on to the pixels.

Textures on each pipeline are required when many textures have to be applied on to a single pixel quickly. This will not have any effect on pixels with single texture.

Core clock speed is normally measured in Mega Hertz. It represents the clock cycle quantity that can be done by the graphics process in a second.

Extra Ports

The graphic card can have many additional ports on its back for easy connectivity with other components and devices. choose according to specific need and requirements. For instance, if you intend to use it along with a digital flat panel monitor, you need to get a graphics card DVI or digital video output. Some graphic cards even have component and S-video output ports compatible with an HDTV or TV so that your personal computer can send signals. Graphic cards with many outputs can allow you to stretch the picture game across more than two monitors.

Graphic cards are sold by many but very few manufacturers are well-known and famous in the market. They are NVIDIA, HP, PNY, EVGA, ATI, MSI, and Matrox.  

We hope that this graphic card buying guide has provided you with great understanding about the various types and brands available in the market. You can make your online purchase after going through the features in relation to the cost of the graphic cards at our site.
