Certified Cable Matters Thunderbolt USB C
Amazon's catalog no longer lists this product (checked 2026-11-02). The name comes from the link HN users posted.
> All USB-C cables do PD. They all do 20V 3A. ALL OF THEM. This is wrong. What FUD.
No you are the one who is wrong. Nothwithstanding optical TB3 cables which can't even carry power, there are a large number of USB-C cables that only do 5V 3A on Amazon such as this one:

> There's no mode other than 40Gbps that is official, from what research I've done. But I do see some cables that list as 20Gbps. To me, this seems like a spec violation, but I could be wrong.

Intel shipped at least 2 controllers that uses PCIe 3.0 x2, which only allows 20 Gbps.
Here is a CERTIFIED TB3 cable only capable of 20 Gbps:

> In practice, nearly all TB3 cables are 40Gbps capable. They will almost completely certainly run USB 3.2 Gen 2x2 more than fine and will run DisplayPort Alt Mode more than fine. They'll do great.
No they won't. Some don't even support USB 3.0 (5 Gbps), especially if they are longer than 0.5m.

"Instead of carrying up to 5 Gbps of USB 3.1 Gen 1 data, these active Thunderbolt cables throttle down to USB 2.0 speeds, offering about one-tenth as much throughput."
