What is USB-C
USB-C is a physical design, and it includes the handy connector end you can’t insert “upside down.” Remember early USB connectors, like those for digital cameras and gaming devices? They had older USB ports you had to plug in facing up. It was also known as USB-A. You may have spent many precious minutes flipping a USB-A connector to get it in the right position.
What is USB 4?
USB 4 has only been around since 2019, making it the newest version of the USB connector technology. It serves as an upgrade over the previous tech and provides better port usage, faster transfers, and "tunneling" of display ports and PCle to external devices. It also uses a Type-C connector, which offers up to 40 Gbps of data transfer and 100 watts of power.
How does Thunderbolt 4 compare?
If USB 4 sounds great, it’s because it is, but it’s not the only technology out there. Thunderbolt 4 offers some of the same perks and is quickly becoming another connectivity standard to beat. It also has a USB-C connection and offers up to 40 Gbps for data transfers.
Currently, you can connect up to 5 Thunderbolt devices to a single PC. It can also support two monitors at a time and requires higher minimum power (15W for Thunderbolt vs. 7.5 for USB4.)
