Thunderbolt 3 vs Thunderbolt 4

All manufacturers need to make sure that they offer the top specifications of Thunderbolt 4 in order to be certified as Thunderbolt 4 by Intel officially. Thunderbolt 4 also supports any USB Type-C monitor with a resolution of up to (7,680 x 4,320) 8K. It means you can use Thunderbolt 4 USB Type-C cable which is much thinner than HDMI or DisplayPort cable to power your high-resolution displays. Additionally, unlike video cables, you can also use a Thunderbolt 4 cable to transfer data and charge devices.

Features of Thunderbolt 4
· Offers 40 GB/s bandwidth.
· Can support one 8K monitor or two 4K monitors.
· Comes with PCIe at 32 GB/s for up to 3,000 MB/s data-storage speeds.
· Offers up to 100-watt PD (Power Delivery) charging.
· Has support for docks with up to 4 ports.
· Allows you to wake your laptop or computer by moving the mouse or pressing a keyboard key if connected with a Thunderbolt 4 dock.
· Comes with Intel VT-d DMA (Direct Memory Access) protection that offers protection against physical DMA attacks.
