Check your motherboard or computer manual if you're not sure. If you can't find any definitive information on the PCI version that your motherboard supports, we recommend buying the largest and latest version PCIe card, so long as it'll fit, of course.
Video game developers are always looking to design games that are ever more realistic, but can only do that if they can pass more data from their game programs into your VR headset or computer screen; faster interfaces are required for that to happen. Because of this, PCI Express won't continue to reign supreme resting on its laurels. PCI Express 5. There are a number of other non-PCIe interface standards being looked at by the technology industry but since they would require major hardware changes, PCIe looks to remain the leader for some time to come.

Tim Fisher has more than 30 years' of professional technology experience. A x1 connection , the smallest PCIe connection, has one lane made up of four wires. It carries one bit per cycle in each direction. A x2 link contains eight wires and transmits two bits at once, a x4 link transmits four bits, and so on. Other configurations are x12, x16 and x Its use may lead to lower cost of motherboard production, since its connections contain fewer pins than PCI connections do.
It also has the potential to support many devices, including Ethernet cards, USB 2 and video cards. In the next section, we'll look at how PCIe is able to provide a vast amount of bandwidth in a serial format. The "x" in an "x16" connection stands for "by. A x16 PCIe connector can move an amazing 6.
At these speeds, a x1 connection can easily handle a gigabit Ethernet connection as well as audio and storage applications. A x16 connection can easily handle powerful graphics adapters. How is this possible? A few simple advances have contributed to this massive jump in serial connection speed:. Interference and signal degradation are common in parallel connections. Poor materials and crossover signal from nearby wires translate into noise, which slows the connection down.
The additional bandwidth of the PCI-X bus means it can carry more data that can generate even more noise. The PCI protocol also does not prioritize data, so more important data can get caught in the bottleneck. But PCIe has even more impressive potential in store for the future of graphics technology. With the right hardware, a motherboard with two x16 PCIe connections can support two graphics adapters at the same time. The cards work together by splitting the screen in half. We don't expect to see products until at least the end of , if not PCIe 6.

PCIe slots are found on many motherboards, letting computer users install components into them. They allow the motherboard and other software in a computer to access and use devices connected to these slots.
While PCIe has been used throughout the first decade of the 21st Century, new slots are likely to replace them at some point in the future. PCI Express is a point-to-point connection, which means it does not share bandwidth but communicates directly with devices via a switch that directs data flow. This allows for "hot swapping" or "hot plugging," which means cards in PCIe slots can be changed without shutting down the computer, and they consume less power than previous PCI technology.
One of the most promising features of PCIe is that it is scalable, which means greater bandwidth can be achieved through adding more "lanes.
