Thanks - I hadn’t heard of this before, but my Macbook seems to predate the chip according to those dates.

Oh wow, I truly appreciate that share. This is the level of detail I was hoping for :D

I had not looked into that but the MBP I want to install Linux on is truly an extra laptop. I get a laptop refresh every 3 or so years from work and get to keep the old one, so at this point I have 2 former work computers so I want to try out the install for the experience. Otherwise I’d just consider recycling it at this point.
