Quote:PC users will have to wait a little longer for PCI Express 4.0 but IBM has the technology ready to ship. We spotted a Wistron P93D2-2P server code named MiHawk at the Adata booth. The server features PCIe 4.0 with up to 64GB/s to the storage backplane from a Microsemi HBA. 16 SATA/SAS and 8 U.2 NVMe SSD ports divide the bandwidth, a 2x increase from a single PCIe 3.0 x16 HBA.

While at Computex we learned from PCI-SIG that PCIe 5.0 has moved to 0.7. The 0.7 revision is just one step away from the final release slated for 2019. PCI-SIG has said in the past that PCIe 4.0 will be short lived due to the quick turn around for 5.0 that again doubles bandwidth. It's possible for PC makers to ignore 4.0 and focus resources on implementing 32GT/s per lane in products coming to market in 2020.
