Finally Intel intends to adopt PCI-Express 4.0 interface released by AMD and its Ryzen 3000 CPU last year, but as usual Intel struggled to adopt it.
Intel and the problem are things that always go hand in hand, and if we add that, they show that "PCI-Express 4.0 is useless for gamers", they are now accelerating PCIe 4.0 support themselves, making it clear industrial form and the solo path taken by Intel.
It is now known that due to delays in the manufacturing process at 10nm and stagnation in the Skylake architecture at 14nm, a new architecture will be launched from here to implement PCI-Express 4.0 can cause waited over a year, and that is why it has now been revealed that the company I want to use your Comet Lake processor to add this interface, and that the new motherboard with LGA1200 socket is ready to support PCI-Express 4.0.
However, PCIe 4.0 presuppose double the PCIe 3.0 bandwidth, which Intel produces with issues related to LGA1200 chipset and platform stability, which forced the abandonment of PCIe 4.0 support with Comet Lake, meanwhile The motherboard is ready to take the leap., because they integrate the necessary components to support new functions.
Meanwhile indicated Comet Lake native support is very goodAn additional external clock generator is required to support this feature, ultimately forcing Intel to drop PCIe 4.0 support from the Comet Lake platform.
Nevertheless, This indicates that some motherboard manufacturers have not given up., and there will be models that offer PCI-Express 4.0 compatibility, but think of Rocket Lake, successor of Lake Comet that will follow at 14nm.
On the other hand, it is indicated LGA1200 motherboards are in the final stages of development., and some manufacturers will drop support for the PCI-Express 4.0 interface entirely to reduce costs it is not known if Lake Rocket will be compatible with LGA1200 socket, which is a great risk that is not necessary for the manufacturer, so if you take a step, it will only be integrated on higher performance motherboards Try to link to higher budget users who are thinking about jumping into Lake Rocket (if it is finally supported).
So in the next few months, We will see some Intel motherboards with PCI-Express 4.0 support that have no function, because Intel Comet Lake will not admit it. Do we have to wait until the end of 2020? receive cpu Tiger Lake @ 10nm +, which will be fully compatible with the PCI-Express 4.0 interface.
