Only where two devices already move large amounts of data between themselves, or where a line arriving faster than a gigabit is being throttled by the socket it lands on. Everywhere else the ceiling is somewhere other than the switch.
This is a question about where the restriction actually sits, and the switch is rarely the answer.
The rates in between, and what they were designed around
Between gigabit and ten-gigabit operation over copper sit 2.5GBASE-T and 5GBASE-T, defined together in IEEE 802.3bz. The design constraint was the cabling already in buildings: 2.5GBASE-T is specified over a Category 5e channel at the full hundred metres, and 5GBASE-T over a Category 6 channel at the same distance.
That is the whole reason the rates exist. Ten-gigabit copper wants a Category 6A channel to reach a hundred metres, and pulling new cable through a finished wall is the expensive part of any upgrade.
Ports negotiate as they always have, so a multi-gigabit socket is compatible downwards and nothing older stops working the day it is fitted.
Where the restriction usually is instead
The line into the building. If it arrives at or below a gigabit, no switch anywhere in the house changes what comes in.
The storage at one end. A copy from a network share finishes at the speed of the slowest element in the path, and on a home network that is very often a spinning disk, an encrypted volume, or a bridge chip inside an external enclosure.
The wireless link. A laptop on a radio is not going to be the device that needs a faster switch port.
The adapter in the machine. Most desktops and nearly all laptops ship with a gigabit interface, and adding one is a purchase in its own right.
The two cases where it genuinely helps
Two wired machines moving large files between themselves. A workstation and a NAS, an editing machine and a server, a backup that runs nightly over the wire. Here both ends can be upgraded, the storage at both ends can keep up, and the link is the thing in the way.
A line above a gigabit. If the connection arriving really is faster than a gigabit, then the router’s WAN socket and the port feeding the rest of the house both have to be above a gigabit or the line is being wasted at the doorstep.
There is a third, quieter case: a wireless access point whose radios are specified well above a gigabit. Its uplink port is the ceiling on everything it serves, and a gigabit uplink is a real limit on a busy unit.
What upgrading actually costs
Running above a gigabit over copper takes more signal processing at both ends, and that shows up as power drawn and heat produced per port. It is why several small multi-gigabit switches are fanless only up to a stated ambient temperature, why others have a fan, and why makers publish a consumption figure for the unit rather than leaving it out.
It also costs a cabling check. The rates name the channel grades they depend on because they depend on them, and a link that will not come up at the higher rate is usually reporting on the cable rather than on the switch.
A sensible order of operations
Find out what the line delivers. Find out what the storage at both ends can sustain — the maker’s sustained figure, not the burst one. Then, if the link is genuinely the narrowest part, buy the ports at both ends and confirm the cabling grade. Buying the switch first is how people end up with a fast socket and the same transfer times.
The manufacturer’s own documentation comes first, and this page is not a substitute for it. Every rate, capacity, class figure, endurance rating, port speed and power figure on this page is reported from the manufacturer's own documentation, with its unit written as published, and named as such — none of it is measured here. A stated capacity is reported as the maker counts it, and is never restated in another unit, because the two are not the same figure. And the statement repeated rather than assumed: a class figure such as AX3000 or BE9300 is the arithmetic sum of the theoretical peak rates of separate radios, a quantity the standard defines rather than one a link produces. No single connection reaches it, and adding the bands together is exactly what makes it large. What a given link carries is settled by the slowest part of the chain, which no comparison page can know.
The questions that come up before an order
Does a faster switch speed up my internet connection?
Only if the line itself arrives faster than a gigabit and the router port it lands on is the restriction. Below that, the line is the limit and every socket in the house is waiting on it. A switch never adds capacity to a connection arriving from outside.
Do both ends have to be upgraded?
Yes. A copper port advertises the rates it supports and settles on the highest one shared with the far end, so a multi-gigabit switch facing a gigabit adapter negotiates a gigabit. The upgrade has to happen at the switch and at the machine, and both have to be on cabling of the grade the rate names.
