Welcher wesentliche Unterschied besteht zwischen PCI und PCI Express?
Der 2003 eingeführte PCIe ist der Nachfolger von PCI, PCI-X und AGP und bietet im Vergleich zu seinen Vorgängern eine höhere Datenübertragungsrate pro Pin. Über die Anwendung für Erweiterungs-Steckplätze hinaus bilden die PCIe-Protokolle inzwischen die Basis für zahlreiche andere Schnittstellen wie SATA Express, M.
Was für ein PCI Express habe ich?
Basierend auf PCIe-Kartenversionen
| Version | Einführung | Übertragungsrate (Durchsatz, x1) |
|---|---|---|
| PCIe 2.0 | 2007 | 5,0 GT/s (500 MB/s) |
| PCIe 3.0 | 2010 | 8,0 GT/s (984,6 MB/s) |
| PCIe 4.0 | 2017 | 16,0 GT/s (1969 MB/s) |
| PPCIe 5.0 | 2019 | 32,0 GT/s (3938 MB/s) |
What’s the difference between PCI and PCI Express?
At the software level, PCI Express preserves backward compatibility with PCI; legacy PCI system software can detect and configure newer PCI Express devices without explicit support for the PCI Express standard, though new PCI Express features are inaccessible. The PCI Express link between two devices can vary in size from one to 32 lanes.
When did the PCI Express 1.0 standard come out?
The original PCI Express 1.0 standard debuted as a replacement for AGP and the original PCI back in 2003 (You can check out the PCIe Wiki if you want to know more about its history). Since then iterations upon PCI Express have continued entering the market, ensuring better backwards compatibility.
What does a PCI Express slot do on a motherboard?
PCIe serves as a high-bandwidth connection between your peripherals and other components. What is a PCIe slot? A PCI Express slot is the physical slot on your motherboard. From smallest to largest, these slots are x1, x4, x8, and x16.
What do the junction boxes on a PCI Express card mean?
white „junction boxes“ represent PCI Express device downstream ports, while the gray ones represent upstream ports. PCI Express ×1 card containing a PCI Express switch (covered by a small heat sink), which creates multiple endpoints out of one endpoint and lets multiple devices share it
