USB-C vs Thunderbolt 5One is a connector. The other is a technology that uses it. Compare layers before numbers.USB Type-C · Thunderbolt 5 overviewUSB 3.2 vs USB4 version 1Compare explicit modes and product support. Neither title identifies an individual port’s performance.USB 3.2 nomenclature and modes · USB4 version 1 overviewUSB 3.0 19-pin versus USB Key-A 20-pin front-panel headersWhich motherboard front-panel USB header form does the board and case cable specify? Connector-family identity is only the first layer; implementation-specific electrical and protocol requirements still need exact documentation.USB 3.0 front-panel 19-pin internal connector · USB 3.1 front-panel Key-A 20-pin headerUSB-C vs USB 3.2USB-C names the connector. USB 3.2 names data modes and nomenclature; a Type-C port does not prove a particular USB 3.2 mode.USB Type-C · USB 3.2 nomenclature and modesUSB-C vs USB4 version 1USB-C is a physical connector; USB4 is a technology. Confirm the exact device and cable instead of assigning USB4 to every Type-C port.USB Type-C · USB4 version 1 overviewUSB-C vs Thunderbolt 4Thunderbolt 4 uses the USB-C connector form, but a USB-C-shaped port is not automatically a Thunderbolt 4 port.USB Type-C · Thunderbolt 4 overviewUSB-C vs USB Power DeliveryConnector shape and negotiated power are different layers. A USB-C port does not by itself establish a particular USB Power Delivery capability.USB Type-C · USB Power Delivery overviewUSB Type-B vs SuperSpeed USB Type-BThe taller SuperSpeed Type-B form is physically distinct from legacy Type-B. Compare the complete outline before choosing a cable.USB Type-B · SuperSpeed USB Type-BMini-USB Type-B vs Micro-USB Type-BMini-B and Micro-B are different connector forms. Similar names do not make their plugs or receptacles interchangeable.Mini-USB Type-B · Micro-USB Type-BMicro-USB Type-B vs SuperSpeed Micro-USB Type-BSuperSpeed Micro-B has a wider compound form. Identify the full receptacle shape rather than assuming every Micro-B cable fits every Micro-B-looking port.Micro-USB Type-B · SuperSpeed Micro-USB Type-BInternal USB 2.0 vs HD Audio front-panel headersIntel’s Thin Mini-ITX examples use different absent-key positions (9 versus 8); a different NUC audio implementation also has another pitch. Never force a 2×5 plug by silhouette.Internal USB 2.0 dual-port header — keyed 2×5, pin 9 · HD Audio front-panel header — keyed 2×5 (Intel example)

Discovery is not a compatibility verdict.

These discovery surfaces route and reorganize facts already represented in the atlas. They do not add electrical ratings, universal pinouts, measured tolerances, exact-device support, wiring approval or an end-to-end compatibility result.
