Both technologies offer significant power delivery, with Thunderbolt 5 supporting up to 240W and USB4 up to 240W. However, the Thunderbolt 5 specification mandates a 140W minimum, while USB4 has no such power delivery mandate even though most USB4 cables support at least 100W PD. The integration of USB4 version 2 with Thunderbolt 5 results in enhanced performance standards, contributing to a unified USB ecosystem that benefits from the strengths of both technologies.
Their overall performance and application also differ significantly. While USB4 is more than adequate for everyday use and offers a robust and cost-effective solution, Thunderbolt 5 caters to more demanding applications with its superior speed and power capabilities. Knowing these differences helps in choosing the right technology for your specific needs.
Data Transfer Speed and Bandwidth
Data transfer speed and bandwidth are crucial in today’s technology landscape. Thunderbolt 5 can achieve data transfer speeds of up to 80 Gbps, with the potential to reach 120 Gbps using its Bandwidth Boost feature. This allows for simultaneous data transfers and bi-directional bandwidth, making it perfect for tasks that require high speed data transfer, such as streaming 8K video or transferring large datasets.
USB4 Version 2.0 has been officially documented by the USB-IF, introducing "USB 80 Gbps" certification logos for compatible cables and devices. Originally announced in 2019, USB4 supports up to 40 Gbps and is compatible with Thunderbolt 3 and 4. USB4 Version 2.0 doubles the speed to 80 Gbps, with the potential for 120 Gbps in one direction for high-resolution monitors. It supports DisplayPort 2.1, powering 4K displays at 240 Hz or 10K at 60 Hz without compression.
Choosing between Thunderbolt 5 and USB4 depends on your specific needs. If your work involves high-speed data transfers or you need to future-proof your setup, Thunderbolt 5 is the superior choice. On the other hand, USB4 provides a cost-effective solution for general use, offering a balance of speed and efficiency.
Power Delivery Capabilities
Both Thunderbolt 5 and USB4 excel in power delivery, with Thunderbolt 5 supporting up to 240W thanks to its adoption of the latest USB Power Delivery protocol via USB Extended Power Range (EPR).
