USB 3.2 & USB-C: What’s the Difference?
Introduction
Since 2015, the USB 3.2 standard (previously known as USB 3.1) and USB Type-C connector have been widely adopted across many electronic devices, including portable SSDs, smartphones, and laptops. However, there is a common misconception that USB 3.2 and USB Type-C are the same.
To clarify, USB 3.2 Gen 1 (previously known as USB 3.0 and USB 3.1 Gen 1) supports data transfer speeds of 5Gbps, while USB 3.2 Gen 2 (formerly USB 3.1 Gen 2) supports 10Gbps. The renaming was part of a rebranding effort by the USB-IF to simplify naming conventions. Meanwhile, USB Type-C refers solely to the connector type, which is compatible with various USB standards, including USB 2.0 and USB 3.2. As one of the leaders in USB connectivity solutions, Newnex has developed this article to provide a clear understanding of these standards and help you choose the right solution for your needs.
Are USB 3.2 and USB-C the Same?
No, USB 3.2 and USB Type-C are different.
USB 3.2 is an industry standard for USB data transfer protocols, building upon earlier versions like USB 1.0, 2.0, and 3.0. USB Type-C is a connector type that can support the different standards. The main highlight of USB 3.2 Gen 2 is its data transfer speed, which can reach up to 10 Gbps, compared to USB 3.2 Gen 1’s 5 Gbps. With the 10 Gbps bandwidth capability, USB 3.2 Gen 2 can offer DP Alt mode, which transfers video display signals directly over the USB cable to support 4K and 8K videos.
| USB 3.2 Gen 1 (USB 3.1 Gen 1) | USB 3.2 Gen 2 (USB 3.1 Gen 2) |
|---|---|

| Data Rate: 5 Gbps | Data Rate: 10 Gbps |
| Backward compatible with USB 2.0 | Supports DisplayPort Alt Mode (DP Alt Mode) for video output |
What Is USB-C?
USB Type-C is the newest connector type, not a standard for data transfer. Unlike the older USB Type-A and Type-B connectors, Type-C features a reversible plug design that fits a variety of compact devices like ultra-thin laptops and smartphones.
However, not all USB Type-C cables are the same. For instance, a USB 2.0 C-to-C cable may appear identical to a USB-C 3.2 Gen 2 cable, leading to confusion. That’s why it's essential to choose cables based on their specifications, not just the connector. For a detailed guide on USB Type-C, visit our USB Type-C Guide.
Key Differences between USB 3.2 and USB-C
- USB 3.2 refers to a data transfer standard.
- USB Type-C refers to a connector type that supports both USB 2.0 and USB 3.2 standards.
- A USB Type-C port does not automatically mean USB 3.2 speeds are supported.
How to Choose the Right USB 3.2 Cable
Selecting the right cable depends on your specific needs. If you're looking for fast data transfer, a USB 3.2 cable might be necessary to support your devices, whether or not it has a Type-C connector. On the other hand, if you need the convenience of a reversible plug and compatibility with newer devices, a USB Type-C cable could be the better choice.
For those seeking high performance and reliability, Newnex offers a variety of USB 3.2 cables capable of speeds up to 10Gbps. If you prefer the compact, reversible design of USB Type-C, Newnex’s USB-C 3.2 Gen 2 & 1 cables provide a perfect balance of durability and performance.
