![]() Thunderbolt 3 (TB3) can reach 40Gbps, but, unlike Apple, some Windows PC manufacturers didn’t choose to offer all TB3’s benefits. Again, look for high device-charging–20W is the best we’ve seen from USB-C. USB-C started at 5Gbps but is also available at up to 20Gbps, although 10Gbps is more common at the upper end. Look out for device charging potential, too, with up to 7.5W on offer with some docks and hubs. Many of the models tested here include faster 10GBps USB-A. USB-A (the old rectangular connector that had to go in one way, usually not the first way you tried) usually maxed at a bandwidth of 5Gbps (USB 3.0) but could be as slow as 480MBps (USB 2.0). They supersede older USB 3.0/USB-A connectors and also slower USB-C variants in terms of speed, but are backwards compatible with USB-C and Thunderbolt 3. ![]() Learn more about the differences between USB-C, USB4, Thunderbolt 3 and Thunderbolt 4. The latest connection standards are Thunderbolt 4 and USB4, which are both based on the neat reversible USB-C connector seen on most new computing devices. We’ve seen prices rising on docking stations due to component shortages, particularly on the Caldigit docks tested here. They are also the best way to add an external display or two to your more mobile computer, plus Gigabit (or faster) Ethernet for wired Internet access.Īll the docks and hubs tested here support at least two external 4K displays at 60Hz a single 8K display (Windows) or a single 6K display (Mac). You will therefore need to connect a multifunction adapter, hub or a more able docking station that includes the ports and slots you need to add extra devices such as hard drives, memory sticks, storage-card readers, printers and so on, as well as wired input tools such as a keyboard or mouse. ![]() Desktop PCs and Macs usually have a decent set of ports at front and back, but laptops and tablets often have just a couple.
