Gen 3 has been around for a while now, but Gen 4 should be out next year, and promises to provide double the bandwidth of the current PCI-e specification (16 GT/s rather than 8 GT/s)

I'm not sure why all this extra bandwidth is necessary, hilariously the first device to support the standard will be a 100Gb/s networking adapter. Fast, but pretty sure it's already doable with the current standard.

I don't see this having a big performance improvement for GPUs, honestly, but perhaps there are uses for it down the road for SSD's and things of that nature?

With the upcoming speeds of XPoint memory and NVME drives, I can see servers saturating PCI rather easily.

The issue at the moment is the bottle neck is going to be he DMI interface.
