TL;DR: I don't think this is the right way to see a CPU's architecture...
Well, I had an old C2D E6420 CPU laying around and thought - why not try and get the heat spreader off and look at the die as I was planning on making a key change from it...
Key word - Was...
I may or may not have - and by that - I did, split the die completely in half. Not a crack, on the face of it. No. A clean slide right through.
Now I know - either I need to be more careful if I do this again or Intel used a solder on this chip... (Pictures in Spoiler)
