Intel unveils the Thunderbolt 4 spec, debuting in PCs in the fall

Intel unveiled Thunderbolt 4 on Wednesday, the next iteration of the I/O specification that provides a high-speed peripheral bus to docks, displays, external storage and eGPUs for PCs. Rather than increase the available bandwidth, however, Thunderbolt 4 provides more clarity and helps create new categories of products.

Thunderbolt 4 will debut later this year as part of Intel’s “Tiger Lake” CPU platform, as Intel originally announced during CES in January. We now know it will support 40Gbps throughput, but with tighter minimum specs. Thunderbolt 4 will guarantee that a pair of 4K displays will work with a Thunderbolt dock, and require Thunderbolt 4-equipped PCs to charge on at least one Thunderbolt port. Thunderbolt PCs will be able to connect to either “compact” or “full” docks with up to four Thunderbolt ports. Longer Thunderbolt cables will be possible, too.
