Question: what is the best ethernet cable for speed?
Answer: Cat5e is rated for 1Gbps and bandwidths of 100MHz, Cat6 offers up to 10Gbps at up to 250MHz bandwidth, and Cat7 can go as high as 100Gbps with bandwidths up to 600 MHz. The other major difference is that Cat7 cables are always shielded, which helps reduce interference and crosstalk.
