Ethernet Cat 8 Speed. Cat 6 has to meet more stringent specifications for crosstalk and system noise than cat 5 and cat 5e. Cat 8 ethernet cables can handle speeds of 25 gbps of bandwidth and up to 40 gbps of transfer speeds.
You may find that your ethernet speed is capped at 100 mbps when your internet service provider, or your internal network connection, should be providing speeds higher than 100 mbps.

Cat5 ethernet cable is the oldest type of these cables.
The new 2ghz speed limit. Cat 8 is defined under both tia and iso, but like the iso cat 7 standard uses shielded cable and different connectors. That speed comes with a price, however, as cat 6 cables are more expensive than cat 5 and cat 5e variants. However, even the cat5e cable in common use supports up to 1 gb/s.
