USB4 is essentially a subset of Thunderbolt 4, mainly designed as an an I/O specification. Thunderbolt 4 allows for longer cables and more Thunderbolt ports on laptops, too.

Thunderbolt 4 supports “wake on sleep” from an external keyboard or mouse, which allows you to tap your external keyboard or wiggle your mouse to wake up your PC, which is handy. For external storage, Thunderbolt 4 supports 32Gbps of data transfer-this really only matters for video, external GPU connections, or possibly games. Thunderbolt 4 doesn’t allow for any leeway-you’re getting a full-fledged 40Gbps connection (32Gbps PCIe + USB 3.2), no questions asked. Thunderbolt 3 is also the only specification (not Thunderbolt 4) that we’ve seen connecting to external GPUs, in case you’d like to try that approach. Thunderbolt 3 also supports a slower (16Gbps) PCIe connection for connecting to external storage. Most manufacturers go beyond this, however, and our recommended docks support the full specification (and two 4K displays) unless noted. “Up to” is the key phrase: Thunderbolt 3 is only required to support a 10Gbps connection, allowing for a single external 4K display (a 16Gbps PCIe connection, paired with USB 3.2). Think of Thunderbolt 4 as the more restrictive version of Thunderbolt 3, with little room for any gotchas.Įssentially, Thunderbolt 3 and Thunderbolt 4 allow up to 40Gbps maximum bandwidth, enough for two 4K/60 displays. The longer answer, which we’ll describe below, is that there are differences, and parsing the nuances can be confusing. The short answer: Not that much, and we consider Thunderbolt 3 docks and Thunderbolt 4 docks to be functionally equivalent for most users.
