It is trivial arithmetic: 4.52403840*2160 ≈ 9 GB/ s. Not even close. Even worse, that cable will struggle to get ordinary 60hz 4k delivered.

4.5 × 240 × 3840 × 2160 ≈ 9 GB/s

It seems markdown formatting ruined your numbers because of the asterisks. Whatever is written between two of those turns italic, so they're not ideal for multiplication symbols here on Lemmy (or any other place that implements markdown formatting).

I think the maths got a bit funky there. I don't think a cable capable of such speeds would struggled to do 60Hz at 4K, it surely doesn't need close to a gigabyte a second?

It surely does. Check pirates post for clean math formatting
