What is Thunderbolt 4 It is the superset standard that includesUSB4®, DisplayPort and PCI Express (PCIe). With Thunderbolt 4, a data transfer rate of up to 40 Gbit/s (at 2 m cable length) as well as 32 GB/s PCIe data transfer must be guaranteed, at least one 100 W charging port must be available and wake-up from sleep mode must be possible.What is the difference between Thunderbolt 3 and 4 Theoretically, a Thunderbolt 3 device should be able to do the same as a Thunderbolt 4 device. However, compared to version 3, Thunderbolt 4 now has to 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 attacksThis is realised through Virtualisation Technology for Directed I/O (VT-d). It prevents physical DMA attacks by protecting PCIe peripherals from unauthorised access to memory using DMA remapping. Access is thus only allowed to an isolated and allocated memory of a specific device.
