The main thing that I like is that it will support dual 4K or 8K displays. This maybe the reason it is so hard to find Thunderbolt 3 adapters that will support dual 4K at 60 Hz easily. A lot of TB3 at 30 Hz. See below for more information.
Intel doubles the minimum bandwidth to 40Gbps in the Thunderbolt 4 specification. That contrasts with the 20Gbps on Thunderbolt 3, which allows manufacturers to cut corners during implementation, failing to take advantage of the full 40Gbps bandwidth. But now, each certified Thunderbolt 4 device must support 40Gbps speeds, so there are no compromises here. https://thunderboltlaptop.com/thunderbolt-4-everything-you-need-to-k...
