| As the new frontier in PCI development, PCI Express technology continues to rise in prominence and is destined to be a killer product that users cannot do without. PCI Express Boasts an Unsurpassable Transmission Speed PCI Express transmission rates reach up to 250 MB/s on a single connection lane. This is considerably higher than PCI and all other types of peripheral data transmission, which have a bandwidth of only 133 MB/s on a shared connection lane. As data transmission occurs sequentially, computer speeds slow down when transferring larger quantities of data. This fact reveals serious shortcomings when Serial-ATA or Gigabit LAN high speed transmission devices use the PCI structure. In addition, with a Northbridge AGP 8X graphics card bus, data bandwidth is 32 bits with a frequency of 533 MHz, with the maximum bandwidth reaching 2.1 GB/s. But with an already-colossal amount of data that continues to grow, the AGP structure faces major changes. Point-to-Point Data Transmission Technology PCI Express uses Advanced Switching, which enables Peer-to-Peer technology and uses physical layer data transmission connections called lanes, which are composed of a sending end (Tx) and receiving end (Rx). Each PCI Express unit has its own transmission lane, which eliminates the need for a shared bus structure and helps avoid data transmission interference. The PCI Express architecture clearly allows for much faster data transmission than traditional PCI. Convenient Hot Plugging FeaturesPCI Express features hot plugging, so while your computer is on, you do not need to remove the computer's outer shell when adding or removing components. These features greatly reduce work time for repairs and provide a long-term guarantee for server maintenance. Additionally, PCI Express supports traditional technologies such as power management, advanced error reporting, and virtual lanes. With a functional design more advanced than the PCI and AGP architectures, PCI Express will continue its march into the mainstream, bringing today's computer bus architectures into a new age. |
