Quick Answer
SA buyers should pay more for Gigabit Ethernet on a dock before paying for extra cable length, because a wired Gigabit port adds stable low-latency networking that Wi-Fi cannot match, while cable length is a cheap fix you can solve separately. A Gigabit-Ethernet USB-C dock at Evetech runs about R1,200 to R1,900. Prioritise the Ethernet port for gaming and video calls; sort cable reach with an inexpensive extension afterward.
Why Ethernet Earns The Extra Spend
A Gigabit Ethernet port on a dock turns a Wi-Fi-only laptop into a wired machine, which matters for online gaming, large file transfers, and stable video calls. Wired removes the jitter and dropouts of Wi-Fi across a busy SA household and makes the most of a fibre line. That capability is worth paying for, since it changes how reliable your connection is day to day. Confirm the port is true Gigabit, not 100Mbps, so it does not cap your fibre.
Cable length, by contrast, is a positioning problem, not a performance one.
a true Gigabit Ethernet dock first, then solve any cable-reach problem with a cheap USB or Ethernet extension rather than an expensive long-cable dock.
When Cable Length Actually Matters
Cable length matters only for desk layout, getting the dock to a comfortable spot, and it is easily and cheaply solved. A modest USB-C extension or a longer Ethernet run costs little and fixes reach without paying a premium for a dock marketed on its cable. So spend the premium where it changes performance, the Gigabit Ethernet port and adequate Power Delivery, and treat cable length as a minor, low-cost detail you handle once the dock is chosen.
FAQ
Is Ethernet or cable length more important?
Ethernet, because a Gigabit port adds stable wired networking that improves gaming and calls. Cable length is a cheap positioning fix solved separately.
How do I confirm a dock's Ethernet is fast enough?
Check the spec says Gigabit, not 100Mbps. A 100Mbps port will cap your fibre line, so it is worth verifying before buying.
What if my dock cable is too short?
Use an inexpensive USB-C or Ethernet extension. Reach is a low-cost detail, so do not pay a premium for a dock sold on cable length.
