What’s the difference between USB 4.0 & Thunderbolt 4.0 – On my Om:

What is the difference between USB 4.0 and Thunderbolt 4.0? How are they similar? Should you care? And what should you look for before buying devices that are certified for one or the other?

Both USB 4.0 and Thunderbolt 4.0 use the same USB Type-C connector which is reversible and rounded. The USB 4.0 is also based on the very same underlying protocol as Thunderbolt 4.0, and both types are tightly connected. All thunderbolt devices come with USB 4.0 support which means if you have a device with Thunderbolt 4.0 connectors you can use USB 4.0 cables.  However, not all the devices with USB 4.0 connectors will be as powerful as the ones that are fully Thunderbolt 4.0 certified. But the good thing about USB 4.0 is that it’s cheaper than Thunderbolt 4.0.
