If all HDMI cables are basically the same design, pinout, etc. how have they been able to double, quadruple, etc. the bandwidth on them over time?

Going from HDMI 1.4 to 2.1 there is a 5x increase is bandwidth. Is it because the cables themselves were never the issue but it was the connectors/chips in the devices themselves that couldn’t handle it?

I know part of it is the actual quality of the cables themselves and tighter tolerances, more twists in the wires, material purity, etc. but I can’t imagine that alone would be enough to fully account for this.

The point is that any cable capable of supporting 2.1 will be as good as any other cable that does so as well, provided neither are outright defective. So look for what version of HDMI the cable is built to support and then pick based on length requirements, color or material (for aesthetics, not expecting better image or sound quality). Overpriced cables that promise better video or audio thanks to their unnecessarily thickness or gold connectors are a scam.
