Ethernet Cat 6 vs Cat 7 Cable: Does It Matter for Gaming?

Quick Answer

For SA gamers, Cat 6 cable is more than enough for any current home or fibre setup, supporting 1Gbps comfortably and 10Gbps over short runs. Cat 7 offers extra shielding but won't lower your ping or boost gaming performance unless you're already running multi-gig networking gear.

What Cat 6 and Cat 7 Actually Deliver

Cat 6 cable is rated for 1Gbps over 100m and 10Gbps over runs up to 55m, plenty for 99 percent of SA homes where a router sits in the lounge and your rig is in a bedroom or study. Cat 7 adds individually shielded pairs and overall shielding, rated for 10Gbps at full 100m. The catch, Cat 7 isn't even an official IEEE standard, it uses non-standard GG45 connectors (though most cables sold as Cat 7 ship with regular RJ45 ends, downgrading them to effective Cat 6A performance). Cat 6A is the proper IEEE-recognised step up from Cat 6, fully rated for 10Gbps at 100m and using standard RJ45 connectors that work with every router and switch on the market.

Will It Affect Your Apex or Valorant Ping?

Honestly, no. Your ping to Apex servers (Frankfurt or Bahrain for SA), Valorant (Frankfurt or Sao Paulo) and CS2 (Stockholm) is dominated by undersea fibre routing, not the metre or two of ethernet cable inside your house. Whether you use a R30 Cat 5e cable from a varsity LAN bag or a R250 Cat 7 premium cable, your in-game ping changes by zero milliseconds. The cable matters for stability and link speed, not latency over the internet. SA gamers see 150ms+ to most Tier 1 game servers, the cable inside your house contributes microseconds at most, well below human perception or competitive impact.

When Cat 7 (or Cat 6A) Actually Pays Off

If you're running a NAS at home, doing 10GbE between a workstation and a server, or have a ridiculously long run through a face-brick wall with electrical noise, Cat 6A or shielded Cat 7 starts to make sense. For pure gaming over 100Mbps to 1Gbps SA fibre lines, you literally cannot use the extra capacity. Spend the cable money on a quality switch or a better Wi-Fi 6E mesh instead. Streamers archiving 4K footage to a TrueNAS box, content creators editing video off network storage, or anyone with a multi-gig fibre line above 1Gbps (rare but rolling out in Joburg and Cape Town through Vumatel) might genuinely benefit from Cat 6A or proper Cat 7.

Practical SA Buying Advice

Stick to a quality Cat 6 patch cable from a reputable brand, around R80 for 3m and R150 for 10m delivered nationwide. Avoid R20 mystery cables from random pop-up stalls, the connectors fail and shielding is often non-existent. Loadshedding is irrelevant to ethernet itself, but a UPS on your router and ONT keeps the line alive through Stage 4 cuts so you don't lose ranked Apex matches mid-ring. For long structured cabling runs through walls and ceilings, hire a network installer to terminate Cat 6 keystone jacks properly, DIY crimping inside walls usually leads to flaky connections that take hours to debug later.

Wi-Fi vs Wired for Competitive Gaming

Even with Wi-Fi 6E and Wi-Fi 7 mesh networks now common in SA homes, wired ethernet still wins for competitive ranked play in Apex, Valorant, CS2 and Overwatch. Wireless adds 1 to 5ms of latency variance plus occasional packet loss spikes when neighbours' microwaves fire up or other 5GHz networks crowd the spectrum. A R150 Cat 6 cable from your router to your rig solves variance entirely. If running cable across a passage isn't practical, MoCA adapters using your DStv coax wiring are an underrated option in SA homes, delivering near-wired performance over existing infrastructure for around R1,500 a pair.

Frequently Asked Questions

Is Cat 8 worth buying for future-proofing?

Not for gaming. Cat 8 is data-centre territory rated to 40Gbps, completely overkill for any home gaming setup in the next decade.

Does cable colour or jacket type matter?

For indoor runs, no. For outdoor runs (e.g. main house to garden cottage), use UV-rated outdoor-grade cable to avoid jacket cracking after one Joburg summer.

Should I crimp my own cables or buy pre-made?

Pre-made patch cables are cheaper and more reliable than DIY for under 10m runs. Crimp your own only for in-wall structured cabling that needs custom lengths.
