With external graphics, gamers can play at recommended visual settings and higher frame rates, even on thin and light notebooks.PCIe connectivity is not supported by USB 3 and is optional for USB4, whereas Thunderbolt™ 4 offers the most flexibility in which devices you can connect. The high bandwidth of Thunderbolt™ 4 allows end users to connect their computers to external GPUs, storage drives, and PCIe enclosures. External Graphics, Storage, and PCIe Enclosures Also connect multiple devices into a Thunderbolt™ hub or dock that can be plugged into a Thunderbolt™ computer to consolidate all accessories into a single connection. Data, power, and video signals can flow from the computer and down the chain into five additional accessories. Daisy Chains, Hubs, and DocksĬonnect multiple Thunderbolt™ devices together in a daisy chain. Compared to the variable speeds of USB4, this requirement ensures that connections are always delivering peak file transfer speeds to support productivity, gaming, and content creation. The Thunderbolt™ 4 standard requires a total bandwidth of 40 Gbps, which it dynamically allocates between data and video for all devices on a single connection. Rich display options: Up to two 4K 60 Hz displays or one 8K 60 Hz display on a single connection 1.

Quick charging: Up to 100W of power for laptop charging and up to 15W for computer-powered accessories.

High bandwidth: 40 Gbps of bandwidth dynamically allocated for data and video, ideal for heavy workloads or fast file transfers.

For example, with a Thunderbolt™-enabled laptop, display, and cable, the laptop can pass a video signal to the monitor and the monitor can charge the laptop at the same time. Thunderbolt™ 4 ports and cables support the trifecta of power charging and data transfer with bidirectional movement and video display in one interface.

Power, Data Transfer, and Video Display in One Productivity, content creation, and gaming applications can all benefit from Thunderbolt™ 4 technology with cleaner workspaces and more bandwidth to support more accessories. Thunderbolt™ 4 offers distinct advantages over USB-C with a more flexible and expansive set of capabilities.
