New to the hardware land, so the core argument here is that CISC instructions are not fixed in length, so decoding becomes less efficient?

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.
