Linus Tech Tips has done some good breakdowns of specific cables so far (with a multi thousand dollar testing rig). They're ramping up to do full testing of all types of cables.

You're right, lots of cables don't do what they say. And it isn't just Thunderbolt. It's HDMI, DisplayPort, USB3, etc. Lots of the HDMI 2.1 cables they tested can only do HDMI 2.0, for instance. Not an issue with Macs, but an issue for lots of Windows gaming rigs.

Exactly. A ~2x premium to make all of that Someone Else's Problem is worth it.

It's a 3x premium over the cables you'd possibly need to be concerned about. The $60 cables just work.

Hmm. My last engagement on this front was before TB4, seems like the situation has markedly improved!
