PCIe 4.0 Standard Will Mean The Death Of Annoying Cable Connectors
PCI Special Interest Group have announced that PCIe 4.0 is almost ready and once it is launched, it is expected to take the world by storm thanks to massive improvements over the current standard.
PCIe 3.0 has been in use in all sorts of motherboards and graphic cards for so long that it feels like we have always been on this standard but that is about to change with the launch of PCIe 4.0 standard. Not only does the new and improved PCIe 4.0 doubles the bandwidth from 8GT/s to 16GT/s but there are also some other amazing new changes in terms of power and performance.
The currently used standard, PCIe 3.0, is capable of delivering up to 75W of power through one of its connector, more than that is just asking for disaster. This is why most graphics cards require additional power through other PCIe connectors using cables. With the launch of PCIe 4.0 however, that will no longer be the case and users can say goodbye to those extra cables.
According to PCI-SIG, the new standard is capable of providing a minimum of 300W and up to 500W of power through just one connector. This ends up being more than enough for any high end graphics card available in the market, even something as power hungry as a GeForce Titan X.
On top of that, the PCIe 4.0 connector will also be backwards compatible so the devices currently supported by PCIe 3.0 connectors won’t become obsolete and should work just fine on the new standard.
This seems like a really great move, especially appreciated by those who think all those extra cables in their system casing are creating a mess even after some top-notch cable management. Coupled with the already announced OCuLink standard which will allow high-end GPUs and SSDs to be used as internal or external devices, PCIe 4.0 means the next few years are shaping up to be great for PCI-SIG.
There are no final specifications for PCIe 4.0 available yet but they are expected by the end of the year.
