PCI Express Video Cards

PCI Express video cards are video cards designed to fit in the small PCI Express slot on a computer’s motherboard. The PCI Express, or Peripheral Component Interconnect Express, is the newest computer expansion slot, and it has become the industry standard since it was first introduced in 2004. Often abbreviated PCIe or PCI-E, this slot replaces the PCI, PCI-X, and the AGP slots as the standard. Many motherboards, however, contain at least one slot of each so that users have many different options. The major difference between PCI Express and these other slots, however, is that they use a topology that features point to point serial links, while the older slots use a shared parallel bus system.

While some peripheral devices still use the older slots, when it comes to video cards, PCI Express video cards are now the default. While many new motherboards have the graphics card integrated (there is no actual graphics card in the computer, it’s all a part of the motherboard), many users who do advanced graphics or play computer games want a more advanced graphics card that can handle more detailed images. These users will most likely get a PCI Express video card. This is especially true if they purchase a video card from top brands like ATI or NVIDIA. Since 2009, both of these companies have began making all of their new video cards for the PCI Express slot and will slowly be fading out products designed for the older slots.

One of the reasons these companies are switching to PCI Express video cards is because the PCI Express slot is capable of higher bandwidth transfer. This allows for companies like NVIDIA to use their Scalable Link Interface. This interface allows users to run multiple video cards that are of the same model together, creating increased performance. ATI has a similar setup called CrossFire that also allows multiple PCI Express video cards to be used together.

A user may expect a PCI Express video card, because it’s better than older cards, to cost more. However, most PCI Express video cards are the same price as or perhaps even a bit cheaper than the older models. In fact, if you walk into a computer store to buy a video card, the majority of the video cards you see will be PCI Express cards. It can be difficult to find a good selection of older video cards. PCI Express video cards are available for standard monitors and for high definition monitors.
