Do TB3 cables wear out?

My monitor saga continues... my set up has been pretty stable bar the odd hic up during set up for a good year or two now, but recently my monitor started losing picture for a split second.

I know the iGPU's struggle at times to drive the 5K's (in windows) but I never had the issue when gaming (as my eGPU took over) but recently I've been losing signal (just picture) in both macOS and W10.

I tried both my 0.5m (passive?) cables and all the ports and while it wasn't predictable the issue persisted.

I've just swapped out the 0.5's for my 2M Caldigit Active cable and, not wanting to tempt fate, all is well.

So, life story shared, with the 0.5 cables previously working but not not do TB3 cables wear and ultimately fail (due to the heat that goes through them)?

Anyone else had issues with older cables? 

Its a bit of a struggle finding Active cables atm for some reason - would love one of those braided 1M ones but they appear out of stock.

Thunderbolt 3 cables are made of baryonic matter which will wear out before the heat death of the universe or sooner if you use it.

There's a metric describing the average number of times a connector can be inserted before it fails (cycles of insertion and removal). The cable with male connectors (plugs) is made to fail before the female connectors (jacks/receptacles).
1.1.1 Durability

I've had problems with a bad DisplayPort cable. As soon as this happens, it goes in the trash.

Mac mini (2018), Mac Pro (Early 2008), MacBook Pro (Retina, 15-inch, Mid 2015), GA-Z170X-Gaming 7, Sapphire Pulse Radeon RX 580 8GB GDDR5, Sonnet Echo Express III-D, Trebleet Thunderbolt 3 to NVMe M.2 case

@joevt

cheers for the reply Joe, a wonderful source of knowledge as ever! (what do you do for work, you seam to have a ridiculous broad and high understanding of all things tech - I often struggle just understanding what you're sharing as it goes way over my head).

I don't feel I've hit 10000 inserts over the 2 years I've had the cables but who knows, the longer active cable appears stable for now so will keep testing it this week and see if it is just a case of trashing the short ones.

 

Thanks again!

@Eightarmedpet, though I would chime in here about my own experience. This concerns an active TB3 cable (2-meter length) made by Mantiz and sold on Amazon.

TL;DR: Mantiz says expected life of an active TB3 cable is one year and typically, stability issues are caused by loose connections on the female side

I started to notice freezes on my laptop using a Razer Core X connected with the aforementioned TB3 cable. Despite driver and firmware updates, this was still occurring. To rule out an equipment issue, I purchased a new active TB3 cable on Amazon (different manufacturer). Using this new cable, I obtained better benchmark scores on SuperPosition (about 2-3% improvement) and the freezes stopped happening. This prompted me to contact Mantiz since the cable is expensive and less than 7 months old (purchased May of 2019).

My TL;DR is based on Mantiz's response, I guess we should budget about $60/year to do a cable swap? Does this pass your common-sense check?

Pending: Add my system information and expected eGPU configuration to my signature to give context to my posts

@ishikawa_goemon hey buddy, cheers for the input! Glad I am not the only one, thought I might be going crackers... I actually bought a new 2M cable and a new 1M cable to have a couple of spares, haven't had any issues so far and I swear animations feel smoother too - I wonder if refresh rate was taking a hit too?
