Have they reached apple m level of performance/watt after half a decade of the apple m parts being out yet? Do either AMD or Intel beat Apple in any metric in mobile?

Yes and yes - again, go look at the published results.

I have, the m4 is significantly ahead by any measure I’ve seen, with snapdragon just behind.

The m4 is not the same fab technology so not comparable. If you want to discuss the validity of some CPU architecture it needs to be between comparable fab technology, M4 being a generation ahead there makes the comparison unfair.

If you compare like to like the difference almost completely disappears.

You mean how they all use tsmc n3 and the two arm parts still beat out lunar lake? It’s not like a whole generational node behind here. I get they aren’t the exact same process node but still.

X elite uses an older node than lunar lake and does better

No they haven't.
