PC World reports Intel is working on a faster version of Thunderbolt that supports the PCI Express 3.0 protocol:
Intel is working to boost data transfer speeds with a faster pipe on Thunderbolt, a high-speed connector technology that link computers with peripherals, the company said on Thursday.
Intel in the future will support the PCI-Express 3.0 protocol to shuttle data faster between host devices and peripherals, an Intel spokesman said in an email. Computers with Thunderbolt interconnect currently communicate with external devices using the older PCI-Express 2.0 technology.
The company will incorporate PCI-Express 3.0 in Thunderbolt, but could not provide a time frame for when it will be accomplished.
