Choosing the right Ethernet cable can greatly impact your network performance. In this guide, we compare Cat 7 and Cat 8 cables based on speed, bandwidth, compatibility, cost, and performance to help you make an informed decision for your home or office network.
| Feature | Cat 7 | Cat 8 |
|---|---|---|
| Max Speed | 10 Gbps | 25–40 Gbps |
| Bandwidth | 600 MHz | 2000 MHz |
| Max Cable Length | 100m (328 ft) | 30m (98 ft) |
| Shielding | Superbly Shielded (Less Interference) | Shielded Foil Twisted Pair (Excellent Protection) |
| Cost | More Affordable | More Expensive |
We conducted several tests using Iperf3 to compare both cables. The results showed:
While Cat 8 boasts higher speeds and bandwidth, **Cat 7 is the optimal choice** for most home and office networks because:
However, if you’re looking to **future-proof your network** for ultra-high-speed internet or data center environments, Cat 8 might be worth the investment despite the higher cost.
For most users, **Cat 7 offers the perfect balance of performance, durability, and cost-effectiveness.** But if your network demands extreme speeds or you want to prepare for the future, **Cat 8 is the way to go.** Consider your budget and networking needs before making the final decision.
so if you're trying to decide between cat 7 or cat 8 for your home or office Network this video will show you which cable is the optimal choice in order to determine the optimal Choice we'll examine each cable and reveal all the specifications pricing and we'll test each Cable's maximum speeds maximum bandwidth multiple streams and UDP Jitter and guys if you don't know this my name is Mike I love technology I love networking I love computer builds I love TVs gaming consoles all things technology if you enjoy these things as well make sure to hit subscribe and the bell notifications and while you're there give a thumbs up and share this video all right first is cat 7 also known as category 7 or class F cabling cat 7 has a maximum speed of 10 gbits per second and 600 MHz of bandwidth and Cat 7 has a max installation run of 328 ft and Cat 7 can run 40 GBS per second from 15 to 50 m and FYI cat 7 is not an official I E standard however cat 7 is a very fast cable so fast indeed that cat 7 can download an entire HD movie in less than a minute and that's amazing of course this is all hypothetical because these speeds depend upon your ISP plan and your home networking infrastructure cat 7 cables are superbly shielded which means it's fantastic at reducing attenuation also known as signal loss in cat 7 is less prone to interference and cross talk from outside sources so this makes it an excellent choice to be installed in your heavy machinery or fluorescent lighting and Cat 7 is backwards compatible which means it's compatible with all your networking equipment and that's good news and then there's CAD 8 also known as category 8 ethernet which is the Undisputed Champion when it comes to speed bandwidth latency and Jitter and just to be clear cat 8 is an official I E standard unlike cat 7 cat 8 speeds are between 25 and 40 gbits per second with an astounding 2,000 MHz of bandwidth and CAD 8 has a max installation run of 30 m or 98 ft and CAD 8 has fantastic shielding inside the cat8 cable you'll find shielded foil twisted pair which is fantastic for reducing attenuation and cross talk so the question is which cable should you choose cat 7 or cat 8 well let's break these cables down and test them when it comes to Speed and Performance cat 8 rules the day but remember those insane speeds depend upon your home network infrastructure your ISP equipment in your ISP Max speeds if your networking equipment is the usual 1 gig or 2.5 gig variety then you won't see much of a difference between these cables as far as maximum cable runs are concerned cat 7 rules the day and that's because cat 7 can be installed up to 100 m and Cat 8 only 30 m and that's over three times the distance as far as compatibility goes both cat 8 and Cat 7 are backwards compatible and both are compatible with all your networking equipment as far as the cost goes cad8 is more more expensive than cat 7 and I'll have a chart right here in the video to show you the pricing as far as durability and installation both cables are the same cat 8 might be slightly thicker but not by much when it comes to gaming both cables should provide a smooth lag-free experience but the most coste effective choice would be cat 7 so guys now we're going to test cat 7 versus cat 8 using I perf 3 we'll test the speeds bandwidth multiple streams and UDP Jitter and here are the results of the ier 3 test after doing the I per three speed tests both cables were identical when it came to speeds bandwidth and multiple streams the only difference was UDP Jitter cat 8 was slightly better than cat 7 but very minimal so the question is which cable is best for your home network cat 7 or cat 8 well the winner is cat 7 cat 7 is the better choice for a multitude of reasons with a maximum transmission frequency of 600 MHz and optimal speeds of 10 gbits per second for over 100 m and 40 GB per second from 15 to 50 m this cable is ideal for Smart Homes or in the business environment demanding high- performing internet connectivity in these speeds rival cat 8 except for the bandwidth also cat 7 cables feature a stricter cross talk specification minimal noise and superb shielding for maximum durability and lastly cat 7 is cheaper than cat 8 which makes it more budget friendly remember the best choice for your setup isn't necessarily the one with the highest specs on paper but the one that aligns best with your home networking demands and budget considerations however there is one caveat if future proofing is your highest priority then install CAD 8 and with that guys make sure to like share subscribe and comment and for God's sakes smash the Bell icon and I'll see you in the next video real soon high five peace
