Cat7 vs. Cat6 Ethernet Speed Test – Is It Worth Upgrading?

Wondering whether upgrading to Cat7 Ethernet will improve your internet speed? In this guide, we’ll compare Cat7 vs. Cat6, perform a real-world speed test, and see if Cat7 is worth it.

Cat7 vs. Cat6 – Key Differences

Feature	Cat6	Cat7
Max Speed	1 Gbps (Cat6), 10 Gbps (Cat6a)	10 Gbps (up to 100m), 40-100 Gbps (short distances)
Bandwidth	250 MHz (Cat6), 500 MHz (Cat6a)	600 MHz
Connector Type	RJ45	GG45
Installation Difficulty	Easy (Cat6), Moderate (Cat6a)	Hard (Thicker, Less Flexible)
Best For	Home Use, Gaming, Streaming	Business Networks, Data Centers

Cat7 Installation and Speed Test

We replaced our Cat6 cable with Cat7 from the fiber ONT to our wireless router and tested our speeds before and after the installation.

Test Setup

• Internet: 1 Gbps fiber
• Before Installation: Cat6 cable (1 Gbps, 250 MHz)
• After Installation: Cat7 cable (10 Gbps, 600 MHz)

Speed Test Results

Test	Cat6 (Before)	Cat7 (After)
Download Speed	940 Mbps	950 Mbps
Upload Speed	940 Mbps	950 Mbps

Does Cat7 Make a Difference?

After testing multiple times, we saw a slight increase in speed with Cat7, but the difference was minimal. If you’re on a 1 Gbps home network, Cat6 or Cat6a is sufficient. However, Cat7 may be beneficial for business networks running multiple applications.

Pros & Cons of Cat7 Ethernet

Pros:

• Higher bandwidth and future-proof
• Minimal noise and crosstalk
• Supports up to 40 Gbps at short distances

Cons:

• Expensive compared to Cat6
• Requires GG45 connectors, not RJ45
• Rigid and difficult to install

Final Verdict

If you're considering upgrading from Cat6 to Cat7, ask yourself:

• Do I need speeds above 1 Gbps?
• Am I running a high-demand business network?
• Is my budget flexible enough to cover expensive cables?

If you answered no to these questions, Cat6 or Cat6a will be a better choice for your home.
