It doesn’t seem particularly likely to be the cables when the same cable plus same external drive but with an Intel Mac results in the expected performance numbers.

In your test, did you use a TB4 cable or a USB data cable?

Just because a marginal cable works on one machine doesn't mean it'll work on another.

I used a USB cable, but I retested with an active TB4 cable with the same results. And again with a passive TB3 cable to the same results.
