What is the PCI Express X16 Card?



PCI Express can be a bit confusing to someone that is used to the older AGP graphics slot. Graphics cards always use a PCI Express x16 slot. The other PCI Express variants are used for other types of peripherals.


PCI Express Lanes


A PCI Express slot is usually defined by the number of "lanes" that it uses. Each lane is a pair of bidirectional serial data lines. In the most recent version of PCI Express, as of 2010, each lane can support 500 megabytes per second in each direction (otherwise known as "full duplex").


PCI Express x16


The standard graphics slot on modern computers is a slot that uses 16 individual lanes at once. This means a x16 slot can transfer data at a theoretical 8 gigabytes per second. However, due to the format that the data is encoded in, there is some loss of speed due to overhead.

On some motherboards, there may be an additional graphics slot in order to enable Scalable Link Interface (SLI). This allows the use of an additional graphics card to improve processing power. However, on some older motherboards, the second slot may not run at the expected x16 speed. The second slot--and sometimes even both slots--may only run at the speed of an x8 slot, while appearing to be a normal x16 slot. This means that the data connection will only run at half speed. Most motherboards built after 2008 do not do this. Anything older, and you'll have to check carefully to make sure you are getting what you expect.
