As we mentioned, each generation or “category” of Ethernet cable is faster than the ones that came before it. Cat7 is capable of supporting a 10 Gbps connection. Cat6 maxes out at a 1 Gbps connection. Cat7 also has additional shielding over Cat6, which can also improve signal quality in addition to more raw speed. That said, Cat7 cables are only faster than Cat6 cables if you have an internet service plan that can reach above a 1 Gbps connection. For many people, the cables will seem to be nearly identical.
