News PCIe 6.0 Specification Hits Milestone: Complete Draft Is Ready


I don't think we will see PCie 6.0 in the time frame they are suggesting on desktops maybe in the server space.
PCIe 4.0 is already stretching the limits of what affordable PCBs can manage, so I wouldn't be surprised if even 5.0 was slow to gain traction in the mainstream due to the overhead cost of either putting retimers everywhere (4.0 can still avoid retimers for the nearest slot) or using much more expensive PCB materials.

I wouldn't be surprised if PCIe went optical before 6.0 gets to mainstream.
