Was bedeutet PCIe x4?
Steckplatz / Slots Manche Motherboards verfügen auch über x4- und x8-Slots. Die Bezeichnung x1, x4, x8 und x16 sagt aus, wie viele PCIe-Lanes in dem Slot kaskadiert sind. Ein x16-Slot kann auch nur 4 (x4) oder 8 (x8) Lanes haben. Bei manchen Boards teilen sich mehrere Slots die Lanes.
Kann eine PCIe x4 Erweiterungskarte in PCIe x16-Slot eingesteckt und betrieben werden?
Die PCI-Express-Spezifikation schreibt vor, dass PCI-Express-x1-Karten auch in x4-, x8- oder x16-Slots funktionieren müssen. Optional können auch x4-Karten in x8- und x16-Steckplätzen oder x8-Karten in x16-Slots arbeiten, aber das ist keine Pflicht.
What does PCIe x16 mean on a motherboard?
If you buy through our links, we may earn an affiliate commission. PCIe x16 is a slot on a motherboard that has 16 data links known as PCIe lanes. This is a slot with the highest throughput rate and can be occupied with expansion cards that have a very high bandwidth requirement such as graphics card.
What’s the difference between PCIe x1 and X8?
Each lane is capable of speeds from 250-1969 MB/s, depending on the version of the PCIe protocol (v1.x, v2.x, v3.0, v4.0). PCIe cards can always operate in PCIe slots with the same or more lanes than the card. For example, an x8 card can operate in a slot with x8, x16, or x32 lanes. Similarly, an x1 card can operate in any PCIe slot.
Which is faster PCIe v4.0 or x16?
PCIe v5.0 is also just around the corner. The key point to note is that every new PCIe version doubles the per lane throughput compared to the previous version. So a PCIe v4.0 x16 slot is twice as fast as the same slot conforming to the PCIe v3.0 interface.
Can a X1 card be used in a x16 slot?
For example, an x8 card can operate in a slot with x8, x16, or x32 lanes. Similarly, an x1 card can operate in any PCIe slot. Sometimes, a PCIe slot operates with fewer data lanes than the mechanical slot-type indicates. For example, sometimes a motherboard manufacturer will use an x16 mechanical slot even though the data connection is only x8.
