|
PCI provides for higher throughput than PCI Express
|
|
|
PCI is a parallel bus architecture and PCI Express is a serial bus architecture
|
|
|
PCI has more communication lanes than PCI Express
|
|
|
PCI is a newer specification than PCI Express
|
Detailed explanation-1: -The main difference between PCI and PCI Express is that the PCI is a parallel interface while PCI Express is a serial interface. PCI is a bus that allows connecting devices inside the computer to extend its capabilities.
Detailed explanation-2: -PCIe (PCI Express®) is the more recently introduced standard for connecting devices to computers. It’s software-compatible with PCI but has higher potential bandwidth and greater flexibility than PCI. The PCIe specification is also maintained by the PCI-SIG.
Detailed explanation-3: -AGP makes multiple requests for data during a bus or memory access, while PCI makes one request, and does not make another until the data it requested has been transferred. AGP doesn’t share bandwidth with other devices, whereas the PCI bus does share bandwidth.
Detailed explanation-4: -PCI and all other kinds of expansion slots use parallel communications, while PCI Express is based on high-speed serial communications. PCI Express is based on individual lanes, which can be grouped to create higher-bandwidth connections.
Detailed explanation-5: -Peripheral Component Interconnect Express (PCIe or PCI-E) is a serial expansion bus standard for connecting a computer to one or more peripheral devices. PCIe provides lower latency and higher data transfer rates than parallel busses such as PCI and PCI-X.
