This article is about what the pcle interface means. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Pcle interface is the latest bus and interface standard, its original name is "3GIO", it is proposed by Intel, it is obvious that Intel means that it represents the next generation of "I hand O" interface standard.

Pcie is the latest bus and interface standard, its original name is "3GIO", it is proposed by Intel, it is obvious that Intel means that it represents the next generation of Imax O interface standard. After it is certified and released by PCI-SIG (PCI Special interest Organization), it changes its name to "PCI-Express", or "PCI-E" for short. This new standard will completely replace the existing PCI and AGP, and finally realize the unification of the bus standard. Its main advantage is its high data transmission rate. At present, the highest version of 16X 2.0 can reach 10GB/s, and it still has considerable potential for development. PCI Express also has a variety of specifications, from PCI Express 1x to PCI Express 16X, which can meet the needs of low-speed and high-speed devices that appear now and in the future. Now mainstream motherboards can support PCI Express 1.016X, and some high-end motherboards support PCI Express 2.016X, such as INTEL's P45, X48 and AMD's 770, 780g, 790X and 790GX as well as Nvidia GF8200. At present, PCI Express has basically completely replaced AGP, just like when PCI replaced ISA, this process has been completed. Although some old users are still using graphics cards with AGP interfaces, AGP graphics cards have been completely suspended on the market, including the motherboard of AGP slots.

PCIE is a higher development of PCI.

At present, the latest version is PCI-E 2.0, and there is also PCI-E (version 1.0) that is not yet out of the market. The AMD RD890 chipset, which will be released in the second quarter of 2009, will be the first to support PCI-E 3.0. 2.0 doubles the bandwidth of 1.0, and 3.0 doubles the bandwidth of version 2.0, which is 5GHz x 4.

The PCI Express 2.0 specification has mainly made a major upgrade in data transmission speed, that is, doubling the frequency of the previous 2.5Gbps bus to 5.0Gbps, which means that the previous PCI Express 2.0 x16 interface can double to an amazing 10GB/s bus bandwidth (1GB/s=8Gbps).

Important upgrade parts of PCI Express 2.0:

1. The key point is to increase the frequency of PCI Express bus: the data transfer rate of each serial line doubles from 2.5Gbps to 5Gbps, and the bandwidth doubles accordingly.

2. It can better support future high-end graphics cards, even if the power consumption reaches 225W or 300W, it only needs to be powered by PCI Express alone.

3. Add "input / output Virtualization" (IOV) technology, which allows multiple virtual machines to share PCI devices such as network cards.

4. PCI-E cable specification enables PCI equipment to access computers through standardized copper cables, and the speed of each line can reach 2.5Gbps, which is suitable for adding multiple network cards as input and output expansion modules for high-end servers.

5. Finally, there is the long-term planning of code name "Geneseo". This technology is developed in cooperation with industry giants such as Intel and IBM, so that coprocessors such as graphics processing unit and encryption processing unit can be secretly connected with the CPU.

6. Improve dynamic link speed and link width management, as well as active power management (ASPM).
