From the perspective of someone else wrapping up a CS degree started after I already landed in the field: If you haven't already taken a dedicated "computer architecture" course (separate from whatever they covered as modules in your standard CS classes) I'd do that first and you'll probably get something out of that. If you have already taken such a course (and enjoyed it) then you might find this fun but I'm not sure on how much it well help in terms of employment knowledge vs more closely related study.
