Tom's hardware got an answer about TB4 from Intel directly at CES 2020 event that Thunderbolt 4 is 4 times faster than USB 3.1 which is 40 Gbps. But why? Both TB3 and USB 4 supports 40 Gbps and it is really confusing to understand the purpose of TB4 without improving the bandwidth. Am I missing something? Is it because it wont gonna use PCIe 4.0?
