It’s mostly that you can only pull instructions off the queue from the front, whereas with ARM since the size is fixed you can just pull them off anywhere.
I think with x86 Intel and AMD are basically brute forcing this by just pulling instructions off a random position and hoping it’s a correct offset, but it’s very inefficient.
