Intel gave the Thunderbolt 3 protocols to the USB Promoter Group, so USB4 offers the same speeds and features, plus backward compatibility.
The USB Promoter Group — an association comprising Apple, HP, Intel, Microsoft, Renesas, ST Microelectronics and Texas Instruments — today announced the pending USB4 specification, slated to deliver 40-gigabit-per-second throughput and support for host-based algorithms to more efficiently handle data operations.
USB4 will use the same USB-C connector we’ve grown used to and still require specific cables to obtain the maximum 40Gbps (5,000 MBps) throughput; with standard cables, it goes up to 20Gbps (2,500MBps).
