I don’t think normal people will ever need Cat7 in their houses, Cat 5e is plenty for most people.
Could you make a video of Cat7 vs Cat5e, or maybe an old Cat5?

The 5e cable is rated at 1 Gb/s, so it should get the same preformace as the 7. The old Cat 5 (non e) is only rated at 100 Mb/s

Do Bo says:

Im using a cat5e cable and im getting 950Mbps on speedtest and 300Mbps uplaod. So cat5e is fine.

DrScopeify says:

Do people still use Ethernet cables in their home? I’ve been wireless since like 2007, 10 years now. Even the company I work at has gone full wireless in the office. We all have laptops so people can meet in focus rooms with colleagues and customers and move around the office without wires.

The commentary is off the chain!

Big Black Anvil says:

Yes it was helpful. Thanks bud.

im sitting over here with 4mbps download and 2mbps upload. FML

John Heyer says:

First rule of networking: your connection is only as fast/good as the worst segment. Even with an old Cat5e you’ll see no difference in this test.

Phillip Watts says:

I’m surprised at how much bigger 50′ of Cat 7 is over 50′ of Cat 6 cable. I didn’t know the Cat 7 was a bigger AWG. Excellent video, thanks!

Caleb Hogue says:

It’s interesting to see that the flat cat6 is 32AWG. I wonder what the test would look like with more traditional cables where cat6 is 24 or 23AWG

Caden Mendes says:

Cat 6 beat cat 7 in youtube

EOSJOE says:

You would probably have seen similar results had you simply ran the same tests multiple times with the same cable. 🙂

pagefour says:

I wonder if we will ever have cat100 14awg. Haha. Maybe in 2047. Haha

James Doherty says:

My company provides 1gig service and we still use cat5e

Mustakrakish says:

In order to test cable bandwidth, you need to ensure that the cables are the bottleneck. In this case, it’s your ISP, not the cables.

The speed limit of CAT6 is 10000Mbps, or 10Gbps. You only have 300Mbps internet service. You would need expensive 10Gbps LAN hardware and 10Gbps internet service (about $300/month plus setup costs) to even test the limits of CAT6, let alone CAT7. You could test the cables with internal network file transfer, i.e. copying a bluray file from one machine to another on the network and timing it, but even that would be limited by your disk read/write speeds and possibly your RAM capacity.

Programmus * says:

But now immagine if you have 200ft of cat7 shielded vs the cat6 not shielded… And you have bunch of electic wire!

Mac Pelao says:

sooo… basically.. save your money and don’t buy cat 7.. no big difference.

Kalif Vaughn says:

I have powerline adapters that get lower speeds in certain electrical outlets (the convenient ones, of course). I suspect it’s due to electrical interference. Do you think Cat 7 would help (Cat 5, Cat 5e and Cat 6 all get similar speeds in my tests). Just curious – and thank you great vid

xSebaceanZx says:

I love it. You should comment the horse racing 😀

GOVAND -K799 says:

Your video is best

Simon Forget says:

I am glad that you are making this comparison on the same basis. However, the end result was expected as the modem and internet connection remained the same and equally subject to network and Internet contention.

I never saw any network cables other than Cat7 to have conductors less than 26AWG. Cat7 cabling requires a minimum of 23AWG, although the gauge might be increased depending on the cable length to prevent conductors to generate heat at high wattages. Network cabling are now subject to NEC beginning with this year revision. We suspect that CEC will follow in their next revision as well. Network cabling was included specifically to address 802.3at Power over Ethernet at level that exceeds 25.5W on voltages between -42 and -57V.

Flat network cables are never use anywhere else than patch cables and, to be honest, I will not be using any. The network cabling standards requires that each pair have to be twisted at a specific pace to mitigate RF crosstalk, thus providing some RF isolation. Starting with Cat7, the standards mandates each pair to be shielded as well. Shielded 8P8C (wrongly known as RJ45) connectors are also mandatory to provide grounding for those shields.

As your modem only provides 1000BaseT on each of its connectors, there is no need for Cat7 cabling except “future proof” if you are welling to bear the higher cost of the hardware.

Bottom line is this test on its own does not and will not provide any proof that Cat7 is superior to Cat6, unless you are testing this under higher data rates and forcing the network hardware to the limit of getting error correction, all of this on a closed, switched network (not depending on a server located on the Internet).

But let’s face it: I’m running NBaseT (5Gbps) rates for some of my equipment on my Cat5E cabling and I do not expect to upgrade the cabling soon. Why? 80% of all network cabling deployed is Cat5E. Standards will continue to evolve to support these low data rates cabling standards, increasing data rates as technology progress.

Keep up your good work.

Glenn Watkins says:

Cat 5E supports gigabit speeds up to 328 feet.

Brad Ryan says:

I find it surprising that the heavier guage and shielding of the Cat 7 cable would not make some kind of difference.  I guess it is a testament to the long term viability of Cat 6.  If I were installing now however, I would use Cat 7 dispite the expense so I could take advantage of the POE.
