What is Thunderbolt™ 4?
It's the superset standard that includes USB 4®, DisplayPort™, and PCI Express (PCIe). Thunderbolt™ 4 requires data transfer rates of up to 40 Gbps (at a 2 m cable length) and 32 GB/s PCIe data transfer, at least one 100 W charging port, and wake-from-sleep capability.

What is the difference between Thunderbolt™ 3 and 4?
In theory, a Thunderbolt™ 3 device should be able to do the same as a Thunderbolt™ 4 device. However, compared to version 3, Thunderbolt™ 4 must now meet much stricter standards to be certified. This includes, among other things, support for two 4K displays or one 8K display.

IB-DK8801-TB4 prevents cyber attacks
This is achieved through Virtualization Technology for Directed I/O (VT-d). It prevents physical DMA attacks by protecting PCIe peripherals from unauthorized memory access through DMA remapping. Access is thus only permitted to an isolated and allocated memory of a specific device.
