Minor nit, but I believe that AMD CPU is 4nm

I believe both M2 and Zen 5 use 4nm. 4nm is just a slightly improved 5nm, though. It's the same process node, not an entirely new process node like 3nm.

Everything I see says the M2 family is 5. Vanilla, pro, max, and ultra.

The nm process for each CPU is listed in technical details on cpu-monkey

Rumors before the M2 release said that it used 4nm.

https://www.macrumors.com/2022/03/10/m2-macs-with-tsmc-4nm-process/

Apple says they use "second generation 5nm technology"

https://www.apple.com/newsroom/2022/06/apple-unveils-m2-with-breakthrough-performance-and-capabilities/

TSMC's website says they have 6 different 5nm nodes: N5, N5P, N5A N4, N4P, N4X

https://www.tsmc.com/english/dedicatedFoundry/technology/logic/l_5nm

So the M2 likely uses N5P, N4, or N4P. N4 and N4P are usually called 4nm in marketing material.

There's probably a leaker out there with more knowledge.

Not trying to start a debate, just saying the specs in the link were different than what was mentioned.

My point is that the M series transition went very well.

Sure, I was just explaining it because the whole 5/4 thing is confusing.
