SANTA CLARA, Calif. – The PCI Special Interest Group will launch an effort in July to created a cabled version of PCI Express that will take on the Thunderbolt interconnect developed by Intel and Apple. Backers suggest the PCIe approach will be more open and more optimal than Thunderbolt for delivering high throughput I/O to tablets and thin notebooks.

The new cable will be based on PCIe 3.0 which supports up to 8 GTransfers/second. It likely will support a maximum of four parallel lanes for throughput up to 32 Gbits/s and distances no longer than three meters.
