GoKawiilApple's USB-C ports vary widely despite identical connectors, explainer clarifies
USB-C refers only to the physical connector shape, not a specific speed or charging capability, while Thunderbolt is a separate standard that happens to use the same USB-C connector on modern Macs. As a result, Mac models differ sharply: a MacBook Air-type machine may offer a 480 Mbps USB 2 port alongside a 10 Gbps USB 3 port, whereas the MacBook Pro M4 Pro includes Thunderbolt 5 ports capable of up to 120 Gbps.
