The Definitive Guide on Choosing the Best Ethernet Cables

Getting reliable, fast network performance starts with having the right Ethernet cable for your specific needs. With so many cable types available, it can get confusing to figure out which one you actually require.

This guide will explain the key differences between Ethernet cable categories, when higher or lower bandwidth cables make sense, and provide tips to match the best cable for your usage case – whether gaming, professional audio-video use, or basic home networking.

A Quick Refresher on Ethernet Cable Categories

Ethernet cables come with speed and performance ratings known as categories, from the basic Cat5 through the latest ultra-fast Cat8 cables. Here is a quick comparison:

Cable TypeMax SpeedTypical Use Cases
Cat5100 MbpsBasic office networks
Cat5e1 GbpsHome networks, online gaming
Cat610 Gbps8K video, high performance networks
Cat710 GbpsAudio/video, harsh environments
Cat840 GbpsFuture corporate/data center networks

Higher rated cables offer advantages like:

  • Faster maximum data rates
  • More protection from electromagnetic interference
  • Increased reliability over longer distances
  • Higher bandwidth for handling multiple devices

But more is not always better. The key is matching cable capabilities with your actual requirements.

Need Blazing Fast Speed? Go With Cat8

If you have a cutting edge multi-GPU gaming rig and 1 Gbps Internet, or need to future-proof your home network, Cat8 is the ultimate choice. These cables are built for speed:

Why Cat8 Cables Are The Fastest

Cat8 cables achieve blistering 40 Gbps transfer rates through:

  • Twisting of internal copper wires to limit signal interference
  • Integrated metal shielding to block external interference
  • Higher 2000 MHz bandwidth rating

With nearly 4x the max speed of Cat6 cables, you can saturate a 10G home Internet connection or smoothly run multiple 8K video streams over Cat8.

Though overkill today, Cat8 cables will stay viable for future multi-gigabit networks and devices. The extra headroom and interference protection also helps for running cables neat sensitive equipment in a dense, high-bandwidth setup.

For Most Needs: Cat6 Offers the Best Balance

While a Cat8 cable may seem tempting for higher speeds, for many home and office setups, a Cat6 Ethernet cable offers the ideal balance of speed and affordability.

Running your Internet into a house? Connecting a desktop PC to your Wi-Fi router? Setting up an office network? For typical uses like these, Cat6 is more than enough:

Why Cat6 Hits the Networking Sweet Spot

  • 10 Gpbs capacity – Matches 1Gbps fiber Internet plans
  • Great pricing – Around $10 for a high quality cable
  • Improved shielding – Rejects noise/interference better than Cat5e
  • Long cable runs – Go up to 100m without signal loss
  • Easy connectivity – Backwards compatible with all network gear

Performance-wise, you would be hard-pressed to exceed what a Cat6 cable can handle in real home use. The shielding also helps avoid interference issues in messier wiring setups.

Targeted Uses Call for Specialized Cables

For niche applications like gaming, audio equipment or outdoor connections, consider cables engineered for environmental resilience and interference reduction.

Why Shielded, Outdoor and Direct Burial Cables Exist

Specialized Ethernet cable varieties improve signal fidelity in challenging installation environments:

  • Shielded (STP) – Metal shielding blocks electromagnetic interference from power lines/motors
  • Outdoor – Waterproof insulation and UV resistance for long-term outdoor runs
  • Direct burial – Rugged sheathing withstands direct underground installation

For audiophile or A/V applications, shielding is vital to eliminate signal distortion from interference. STP cables lock in perfect quality.

Outdoor or direct burial cables allow permanent connections in outdoor areas without having to run conduit.

On a Budget? Go With Value-Minded Cat5e

If you just need a basic patch cable to connect devices in close proximity, it‘s hard to beat affordability of Cat5e Ethernet cables:

Why Cheap Cat5e Cables Still Get The Job Done

  • Costs just a few bucks for shorter cables
  • Still offers 1 Gbps capacity – Same as Cat6!
  • OK for basic home/office networking
  • Good for short patch cable runs like modem to router

With Ethernet cables, while shielding and peak speeds get the hype, even cheap copper lines without fancy features work surprisingly well for general computing and Internet access purposes.

Just don‘t try to run long cables for high-throughput uses like streaming uncompressed video, where bandwidth and interference rejection become more critical. Stick closer to the 100 meter maximum length specification.

Bottom Line

Still overwhelmed trying to pick out which specific Ethernet cable you need? No worries – let‘s boil it down to the key deciding factors:

  • For typical home uses, start with Cat6 – best value for performance
  • To future-proof higher Internet speeds, consider Cat8 capacity
  • If you have interference issues, choose a shielded STP cable
  • Prioritize shielding for audio/video signals requiring perfect fidelity
  • Don‘t overpay if you just need short patch cables in your office
