I vaguely remember Intel tried to get into the low power / smartphone / table space at the time with their Atom line [0] in the late 00's, but due to core architecture issues they could never reach the efficiency of ARM based chips.

I don't think it was core architecture issues. My impression is that over the years their efforts to get into low-power devices never got the full force of their engineering prowess.
I worked for an IP vendor that was in some Atom SoCs (over a decade ago now though) - from what I remember the perf/w was actually pretty competitive for contemporary ARM devices when we supplied the IP, but then took so long to actually end up in products it ended up behind others - other customers were already on the next generation by that point, even if the initial projects started at about the same time. And the atoms were buggy as hell, never had more problems with dumb cache/fabric/memory controller issues.
To me the Atom team always felt like a dead-end inside intel - everyone seemed to be trying to get in to a different higher-status team ASAP - our engineering contacts often changed monthly, if we even knew who our "contacts" were meant to be at any time. I think any product developed like that would struggle.
