Thunderbolt 5 will debut in 2024, both in laptops as well as docks and devices. The spec pushes I/O bandwidth from 40Gbps in Thunderbolt 4 to 80Gbps in Thunderbolt 5, and even to 120Gbps in some cases. Another good way to think of Thunderbolt 5 is in the context of what it can do. Thunderbolt 4 allows enough bandwidth for two 4K displays, running at 60Hz. Thunderbolt 5 will offer enough bandwidth to connect to three 4K displays, at 144Hz apiece. That helps make Thunderbolt 5 a gaming-class technology, rather than just for office work. Thunderbolt 5 will also allow for 64Gbps of dedicated bandwidth for storage and external GPUs, double the 32Gbps on Thunderbolt 4. Finally, there's power. Thunderbolt 5 will provide up to 240W (140W required) of charging power for your laptop. Most laptops require 65W to 90W today, but gaming laptops require more. All this means is that a Thunderbolt 5 dock will potentially eliminate the need to carry a gaming laptop's charger around. (It won't be in all cases, but some.)
