I don't know why I'm just reading about, and thus reporting about it just now, but more details are leaking out on next iteration of the PCI Express specification - PCIe 4.0.
As it stands, PCIe 3.0 has a maximum throughput bandwidth of 32GB/sec, but PCIe 4.0 will ramp things up to 64GB/sec - as it will have a base speed of 16Gbps per data link. At the moment, GPUs won't make much more use of this, but with SSDs moving toward PCIe - we are seeing a huge increase in the required bandwidth - with OCZ showing off 3.8GB/sec with PCIe-based SSDs in RAID 0 at Computex this year as an example.
When will we see PCIe 4.0 rolled out? We should expect it to come baked into Intel's upcoming Skylake platform, with its 100-series chipset.
