What Is PCIe?
Intel officially renamed 3GIO to Peripheral Component Interconnect Express on July 23, 2002.
Its interface varies depending on the bus width.
The PCIe 1.1 introduced in 2005 only made some improvements without improving the data rate.
PCIe 2.0 has improved the point-to-point data transfer protocol.
It can provide data rates per lane up to 4 Gbit/s from its raw data rate of 5 GT/s.
In addition, PCIe 3.0 also supports backward compatibility.
PCIe 3.0 also optimizes enhanced signaling and data integrity.
In a 16-channel configuration, 63GB/s is produced in each direction.
In addition, the PCIe bus supports bidirectional transmission mode, providing higher transmission rates and quality.
It uses trusted flow control.
The connection between the two PCIe devices is the link.
Apply of PCIe
PCIe is used in consumer, server and industrial applications.
In 2005, almost all personal computer motherboards used PCIe.
As of 2013, PCIe has successfully replacedAGPas the default interface for graphics cards on new systems.
