After seeing that my wireless speeds were much faster than the speeds I was getting over Ethernet, I decided to invest in some new cables. I didn’t know it before, but I saw while I was changing them out that my current cables were Cat 5e. While putting my network together, I had just been grabbing whatever cables I could find in my scrap drawers. Now I have Cat 8 cables and my speeds jumped from 7MB/s to an average of over 40MB/s. It’s a much bigger improvement than I expected, especially for such a small investment.
Yes but… tests are done in controlled environments and ideal conditions, there are big real world differences with CCA vs fully copper or those solid core options vs stranded ones. They’ll all perform differently depending on distances, noise immunity will vary and will break differently in different ways when tension is applied. You can also get Cat5e on different AWG sizes, all spec compliant but all very different from each other.
The bottom line is: it all comes down to how much you’re willing to spend.
