Below is a table of the bandwidth results.
CAT5e | Powerline Ethernet |
---|---|
637 Mbits/sec | 73.4 Mbits/sec |
629 Mbits/sec | 74.0 Mbits/sec |
612 Mbits/sec | 74.5 Mbits/sec |
My tests were conducted to favor the Powerline Ethernet adapter. I placed the two Powerline Ethernet adapters within 8 feet of each other in the same room. No extension cords were involved. The CAT5e circuit was a couple of hundred feet and include 2 Ethernet switches between the computers.
Here is the raw output from the

Here are the specs on the Ethernet adapter in the client computer. Notice it has negotiated at a gig with the Ethernet switch.
