USB 4.0 is now published. The new standard calls for:
- Two-lane operation using existing USB Type-C cables and up to 40 Gbps operation over 40 Gbps certified cables
- Multiple data and display protocols that efficiently share the maximum aggregate bandwidth
- Backward compatibility with USB 3.2, USB 2.0 and Thunderbolt 3
Existing Type-A ports will continue to exist while the transition moves forward. The front panel box in the HAF 932 offers a Type-C port so that devices can be connected easily.
The PC already has began to transition to Type-C. The X570 motherboard has a Type-C port at the I/O shield. More Type-C ports are inevitable as more hardware becomes available.
New high bandwidth cables will be available in a few months. The existing charger cables are adequate for lower bandwidth needs.
