英语翻译
For users,this means significantly improved I/O performance and,thus,application performance specially for demanding applications.Because all traffic routing and resource management is centralized in a single switch,and because of PCI Express'' packet-based communication model,the switch can give higher priority to certain types of traffic such as video or audio streams.For systems designers,PCI Express means lower costs and simpler design because each pin has far greater bandwidth.
PCI Express provides for future scalability both in bandwidth (by increasing the number of lanes available),as well as the frequency of the bus.Most server and desktop systems now shipping support PCI Express cards with up to 8 lanes,but the architecture supports as many as 32 lanes.This scalability,along with the expected doubling of the speed of each lane up to 5Gbit/sec.,should keep PCI Express a viable solution for designers for the foreseeable future.

对于用户来说,这意味着显着改善I / O性能,因此应用性能专为要求苛刻的应用.因为所有的交通路线和资源管理是集中在一个单一的开关,并且由于PCI Express的''基于分组的通信模型,该开关可以提供更高的优先某些类型的交通,如视频或音频流.为系统设计师,PCI Express的手段,更低的成本和更简单的设计,因为每个管脚具有深远的更大的带宽.
PCI Express的规定,为未来的可扩展性无论是在带宽（由数目增加车道可用） ,以及频率的巴士.大多数服务器和桌面系统,现在航运支持的PCI Express卡与多达8个车道,但架构支持多达32车道.这可扩展性,随着预期增加一倍的速度,每里最多5gbit/sec ,应保持PCI Express的一个可行的解决办法,供设计为可预见的将来.
