Review on 🔌 High-Speed Intel-Certified 20Gbps Thunderbolt 3 Cable - 6.6 Feet (USB C Thunderbolt Cable) in White with 100W Charging Support by Clete Dean

If you want to use this as just one straight run to one device you should be fine at this being half the cost of active cables , but unfortunately that was not my use case. Tried to use this in a daisy chain setup where it failed to allow any device past the first to properly show up. An Apple Thunderbolt Display couldn't be detected, nor could a TB3 dock from OWC, nor an Akitio thunderquad external ssd/hd array when plugged in behind the first device. Switching back to a 40gbps short passive cable or longer active cable both allowed daisy chaining out to 6 tiers as promised, so I would be careful if purchasing one of these to make sure you won't at some point need device pass through.Important to read up on the differences between thunderbolt and USB standards as it's a bit of Wild West out there, particularly on Revain where cables present themselves as one thing that is misleading to those uninitiated in the woes of donglehell.Here's a TLDR:USB Type C cables have the same basic shape, but depending on how they are wired and/or chipped, they use different communication standards.USB 1.0 - haven't seen any of these in the wild, so they are likely to be the bottom barrel cheapies you might find in a gas station since most of even the cheapest are at least USB 2.0. 1.5Mbps. So slow that it's really only useful for something like a keyboard or mouse (faster than the old ps2 connector that looks like s video)USB 1.1 - same as above, but 12Mbps.USB 2.0 - most cables that come in the box with a phone or computers follow this standard. 480 mbps. Note that's bits, not bytes (a bit is 1/8th of a byte), so that data rate is misleading. Even the apple cable that comes with modern MacBooks is limited to this data speed. Fast enough for something like an audio interface without too many input channels.USB 3.0 - Normally usb type A (the one you're used to that's rectangular) that has 3.0 has blue on the inside of the plug to indicate it's 3.0. This standard is faster than 2.0 to a good degree and it's probably the most common even in 2020. 5Gbps speed at this point, enough to allow a USB hub that lets many input/outputs happen simultaneously. Just fast enough for HD video, but nowhere near enough for 4k in realtime.USB 3.1 gen 1 - Capable of sending more power through the cables (100w) and same data rate as USB 3.0, but not backwards compatible with USB 2.0 and before. 5Gbps data speed.USB 3.1 gen 2 - aka Superspeed - this has twice the data throughput of gen1, no backwards compatibility in terms of cables and the same power limit. So 10gbps, equivalent to the original thunderbolt standard in terms of data throughput. Note that if you buy a type c cable that is usb 3.1 gen 1 or gen 2, it won't work with many USB Type C devices like a Logitech mx mouse, or mass drop alt keyboard as they use the 2.0 usb standard for data and power over type c cables.Thunderbolt 1 - 10gbps, this was carried over Mini DisplayPort cables. It seems like thunderbolt cables were the same, but the hardware on computers or devices that deciphered things was either TB1 or TB2, so you probably can't find a type c cable that is thunderbolt 1.Thunderbolt 2 - This is the fastest a minidisplayport connector thunderbolt cable can get. At 20gbps it is still faster than the fastest current USB connections. Enough to daisy chain 6 devices and enough for 4k video at realtime. On type c however, it does not appear to support daisy chaining, to my chagrin.Thunderbolt 3 passive - these are the little cables that come with many docks and whatnot, They use all their little pins to be able to achieve 40gbps data, and 100w of power, while still being backwards compatible as much as possible. They still don't appear to work with USB 2.0 and below however.Thunderbolt 3 active - these cables sacrifice backwards compatibility with some USB standards to use some juice for boosting the signal and making longer cables still able to run @ 40Gbps. If you buy an LG TB3 monitor or the XDR display from Apple you get one of these at it's longest run, 2m or about 6.6 feet. These seem to start at $60 and go up in price to around $100. Apple doesn't even sell one despite including a nice one with the XDR monitor.Thunderbolt 3 optical - these are the same as above, but use a computer chip and fiber optics to run really nice long runs of full 40Gbps speed down line in ridiculously long runs. They also cost $400 and up.On top of all this, cables can have different power delivery standards, as well as different digital to analog converters if you are talking about a headphone jack to USB Type C. If you have a complicated run planned, expect to do your research and still have to buy and return cables like this that have limitations even good research won't disclose. Good luck.
