  • Cat5e: 1 Gbps.
  • Cat6: 10 Gbps.
  • Cat7: 10 Gbps.
  • Cat8: 40 Gbps.


When considering performance, bandwidth plays a role in the comparison of Cat5e Vs Cat6 Vs Cat7 Vs Cat8. Cat5e has a bandwidth of 100 MHz, while Cat6 boasts 250 MHz. Cat7 goes up to 600 MHz, and Cat8 performs top-notch with 2,000 MHz bandwidth.

For gaming or streaming, higher speed and better bandwidth mean less lag and buffering. This is why many choose Cat6 or higher cables for these activities.

  • Cat5e: 100 MHz
  • Cat6: 250 MHz
  • Cat7: 600 MHz
  • Cat8: 2000 MHz

Distance and Installation

Each cable’s distance capability varies. Cat5e and Cat6 cables can both send data up to 100 meters, but Cat6 excels in shorter runs for faster speeds.

Cat7 supports 100 meters, too, but does a better job with shielding and reducing interference. Cat8 is effective up to 30 meters.

Installation might differ based on shielding. Cat7 and Cat8 lack RJ45 plugs, and they often need specialized connectors like GG45. This means you might need a different setup.

Uses and Applications

Each cable fits different uses. Cat5e is suitable for basic home networking. Cat6 meets the need for high-speed activities such as gaming.

For more intensive tasks, Cat7 offers improved resistance to crosstalk and interference. Cat8 is perfect for professional uses, especially where the fastest data transfer speeds are critical.ethernet

Cost Considerations

Cost is an important factor in the comparison of Cat5e vs. Cat6 vs. Cat7 vs. Cat8. The cost increases with the higher categories. Cat5e is the most affordable, while Cat8 can be quite expensive. It’s essential to consider whether the price aligns with your requirements.

While upgrading to higher categories can be beneficial, it also depends on your internet service provider. Some connections might not fully utilize the capabilities of a Cat8 cable.

Pick the right cable based on your priority. Whether it’s basic browsing, high-speed gaming, or professional networking, there’s an Ethernet cable that fits the bill.

Is CAT7 or 8 better for gaming?

Cat7 ensures a more stable connection during your gaming sessions because of low interference and high speed. Less lag and smoother gameplay make Cat7 a solid choice.

Cat8 cables take it up a notch with speeds up to 40 Gbps. If you’re into high-speed gaming and streaming simultaneously, Cat8 could be beneficial. However, remember that most home networks won’t use the full potential of Cat8.

When thinking about cost, Cat7 is generally more budget-friendly. If your internet plan is less than 10 Gbps, this could be enough for a premium gaming experience. Higher expense with Cat8 might not be justified.

In most cases, Cat7 strikes a good balance between performance and cost. For most gamers, it’s more than sufficient. Save Cat8 for specialized setups where you truly need top-tier performance.

Is Cat8 overkill?

Cat8 cables are usually meant for data centers and professional settings. They provide excellent performance with a high bandwidth, which excels with tasks requiring high-speed data transfers and minimal interference.

For regular home use, Cat8 might be overkill. If your internet plan is less than 1 Gbps, you won’t fully benefit from Cat8. In such cases, Cat6 or Cat7 could be more practical.

The cost of Cat8 cables is also higher. For most home networks, this might not be worth the extra expense. Save your money unless you really need that ultra-fast speed.


Can I use Cat7 or Cat8 with my existing equipment?

This is possible as long as your device is compatible with higher speed. Otherwise, you won't benefit from the full capabilities of Cat7 or Cat8 cables.

Is Cat7 or Cat8 overkill for home use?

For most households, Cat6 is sufficient. Cat7 and Cat8 are more suited for specialized or professional environments needing extremely high speeds and reduced interference.

Which Ethernet cable is better for gaming?

Cat6 is good for gaming as it transmits data at a high pace and ensures a stable connection. If you need higher speeds and greater stability, Cat7 might be a good choice.

Do all Ethernet cables use RJ45 connectors?

Most Ethernet cables use RJ45 connectors, but Cat7 and Cat8 sometimes use GG45 or TERA connectors due to their enhanced performance needs.

Does Cat9 cable exist?

No, according to the latest information, there are no ethernet cables beyond Cat8.

Can a Cat5 run 1000 Mbps?

While Cat5 cables can only handle speeds up to 100 Mbps, Cat5e can easily transmit 1000 Mbps, or 1 Gbps. This upgrade makes it more reliable for today's internet use.

Is Cat8 bad for gaming?

Whether Cat8 is bad for gaming is a common question. The simple answer is, it's not bad, but it might be overkill. Cat8 cables offer incredibly high speeds, up to 40 Gbps.

Is Cat8 good for home use?

No. Even though Cat8 can easily handle the network requirements of a home, most its functionalities will be wasted on a home network.

Does Cat8 use RJ45?

Wondering if Cat8 cables use RJ45 connectors? The answer is yes. Cat8 cables are compatible with RJ45 connectors, making them easy to use with most devices. This is great because RJ45 connectors are standard for Ethernet connections. So, you can easily replace older Cat5e, Cat6, or Cat7 cables with Cat8 without needing special adapters. This compatibility makes upgrading simple and hassle-free.

Can I use RJ45 for Cat7?

Wondering if you can use RJ45 connectors with Cat7 cables? The answer is yes, you can. However, there's more to consider. Cat7 cables often use GG45 or TERA connectors for optimal performance. These connectors help reduce interference and maximize speed. But, RJ45 connectors are still backward-compatible with Cat7.

How does Cat6 differ from Cat6a?

Cat6 both offer speed of upto 1 Gbps, but the difference is the range. Cat 6 extends to a distance of 55 metres while Cat6a covers a distance of 100 metres. The improved performance of Cat6a comes from better shielding against interference. This makes it a great choice for environments with high electronic noise.

Is it worth upgrading from Cat5e to Cat7?

If you require higher speeds or reduced interference, upgrading to Cat7 can be beneficial. Cat7 supports speeds up to 10 Gbps with superior shielding compared to Cat5e. This upgrade offers more reliable performance for gaming or high-definition streaming but may not be necessary for basic tasks.

Can I use an old router with new Ethernet cables?

You can use newer Ethernet cables with older routers, but you won't get maximum benefits unless the router supports high-speed connections too. For example, connecting a Cat8 cable to an outdated router won't provide top speeds. Ensure your router is capable of handling higher speeds if you're investing in advanced cables like Cat6 or Cat8. This way, you make full use of their capabilities.

Are all Ethernet cables backward compatible?

Yes, newer Ethernet cables like Cat6, Cat7, and Cat8 are backward compatible with devices that support older standards like Cat5e. This means you can upgrade your network incrementally without replacing all equipment at once. This flexibility allows you to enhance your network's performance step by step while keeping costs manageable. Start with critical upgrades and expand as needed!
