computer: ATI Radeon HD 5850 – DirectX 11 graphics card

A graphics card (also video card) is a piece of hardware installed in a computer that is responsible for rendering the image on the computer’s monitor or display screen. Graphics cards come in many varieties with varying features that allow for a price range that extends from about $20 US Dollars (USD) to $2,400 USD or more.

The new ATI Radeon HD 5850 is the next-generation desktop graphics cards,part of the AMD’s ATI Radeon HD 5000 series of GPUs.It supports Microsoft’s upcoming DirectX 11 API.

Prepare to experience a riveting high-definition gaming experience with the new ATI Radeon HD 5850graphics processors.Expand your visual real estate across up to three displays and get lost in the action with revolutionary ATI Eyefinity Technology. Using ATI Stream technology, accelerate even the most demanding applications and do more than ever with your PC.The first to deliver full support for Microsoft DirectX® 11, these GPUs enable rich, realistic visuals and explosive HD gaming performance so you can dominate the competition.

The first consideration when buying a graphics card is to be sure it is capable of displaying the best resolution the monitor can support. For Liquid Crystal Display (LCD) monitors this means supporting the native resolution. Cathode Ray Tube (CRT) monitors do not have a native resolution. In this case, ensure the graphics card is capable of supporting the highest resolution, even if the CRT monitor will be frequently used at lower resolutions.

The second consideration is on-board memory. A graphics card must work very hard to render images to the screen. Unlike text files, graphics images are much larger files consisting of great amounts of data that must be processed by the graphics or video card. A faster graphics card has its own resident memory chips to perform this function so as not to impinge upon the system’s random access memory (RAM). Less robust graphics cards have less resident memory and require sharing system RAM to process images.

The graphics processing unit (GPU) is a chip akin to the computer processing unit (CPU). The GPU on the graphics cardprocesses data in parallel lines called “pipelines.” The more pipelines a graphics card has, the faster it can process data. Some cards feature dual GPUs for additional performance. Other factors that play into performance include bus speed and the type of on-board memory the graphics card supports.

Because graphics cards work hard they generate heat. For this reason most high-performance video cards utilize built-in fans. Fans can be quiet or noisy, depending on the card model. High-performance fanless video cards are also available. These cards use heat syncs to pull heat away from the GPU. The advantage of a fanless graphics card is lack of noise; disadvantages include expense and a wider footprint that can take up two slots inside the computer.

Installing a graphics card is very easy. The card features an interface that plugs into a port or slot inside the computer on the motherboard. Older motherboards offer an Advanced Graphics Port (AGP) interface, while newer boards have the faster Peripheral Computer Interface Express (PCIe) interface. A PCIe graphics card cannot be installed into an AGP slot, and visa-versa, so be sure to get a card that is compatible with your system.
