In the overview below you can see the differences:

Cat5e Has a speed to 1.000 Mbit/s, 100mhz

Cat6* Has a speed to 1.000 Mbit/s, 250mhz

Cat6a* Has a speed to 10.000 Mbit/s, 500mhz

Cat7 Has a speed to 10.000 Mbit/s, 1.000mhz


The big difference between Cat6 and Cat7 is the frequency. As you may have already seen, a Cat7 cable and a Cat6 cable have the same speed. However, the Cat7 has a higher frequency than the Cat6.

The frequency indicates how often the signal can pass through the cable.

At a frequency of 1,000 MHz, 10,000 Mbit / s can therefore be transferred 10,000 times per second 10,000 Mbit / s.*

A Cat7 cable will therefore be able to transfer data faster than a Cat6 cable.

Speed is irrelevant especially with only a gigabit router.
In practice, a well made cat 5e cable can support 10Gbps speeds at a short distance.

most ethernet cables you buy from a store/online are not even up to specifications e.g using copper clad aluminum instead of solid copper for the cables and in the case of those flat ethernet cables, no shielding, no cable twist to prevent crosstalk etc
