PCI Express (PCIe) is the latest interface specification designed to improve a system's graphic performance by increasing its bandwidth. It helps speed the communication flow between the CPU and the graphics controller. This enhancement allows texture maps of greater size, detail, and realism enabling 3D applications to run faster because of even higher bandwidth compared to AGP.
An Intel PC bus architecture that doubles the bandwidth of the AGP 8X bus, delivering over 4GB per second in both upstream and downstream data transfers. The graphics processing unit (GPU) has the largest bandwidth appetite of all PC subsystems, and from the start NVIDIA has been a key contributor to the PCI Express architecture, as a developer, a supporter, and as a provider of PCI Express graphics solutions.
First came PCI, then PCI-X, then PCI Express. PCI Express can be abbreviated ...
Local bus standard that offers faster speeds than PCI and AGP.
A high-speed peripheral interconnect introduced in 2002. Note that although abbreviated "PCX", PCI Express is not the same as "PCI-X". Intending to eventually replace the PCI and AGP buses entirely, PCI Express was designed to match the higher speeds of today's CPUs.
PCI Express is the latest interface for connecting a graphics card to a computer system, and it is the successor to AGP in terms of gaming graphics performance.
The successor to the PCI slot, and will become the new standard for connecting peripheral cards to the PC in the next few years. Unlike the PCI bus, PCI Express is a serial bus.
New standard replacing PCI and AGP.
An evolutionary version of PCI that maintains the PCI software usage model and replaces the physical bus with a high-speed (2.5 Gb/s) serial bus serving multiple lanes.
An implementation of the existing PCI computer bus, but it is much faster
A high-speed, serial connection interface between a graphics card and a computer Page Top
Implementation of the PCI bus based on a much faster serial physical-layer communications protocol.
PCI has been a local interconnect technology of choice in communications and embedded applications over the last decade. Today's applications demand higher bandwidths that push the limits of parallel bus architecture. PCI Express is a high-bandwidth, low pin count, serial, interconnect technology that also maintains software compatibility with existing PCI infrastructure, and is uniquely positioned as the logical interconnect technology for products being developed today.
PCI Express (Official abbreviation PCIe, PCI-E often used) is a computer system bus that allows expansion cards with various capabilities to be added to a system. It is an updated implementation of the Peripheral Component Interconnect standard.
