Am I the only one who's going to point out that if you look at die shots of current AMD processors there seems to be so many 'blotches'? This is true for the cores themselves and many blocks of the surrounding logic, which look even 'blotchier'. This seems to be a characteristic of AMD's high density library which they began using with Bulldozer (I noticed this blotchy structure in Zambezi in the Vcc Gating Footer next to the core, and this has been an increasingly common sight in Steamroller and Excavator, and even more so with Summit Ridge.
I'm sure Intel has noticed this also and may be planning something similar in their top secret future CPU core, if they feel that this design philosophy has advantages over traditional methods. I've been staring at die shots in my sleep so when Zen came out I've been almost baffled by the die shots. They're nothing like die shots from earlier integrated circuits, CPU or otherwise. Very curious.
Would also be interesting to see some microscopic shots of these blotchy (from afar) structures.
Edit - feel free to click on the images below for more detail. Look at those features. It's like someone vomited all over the CPU die!! Sorry I know it's gross but that's what comes to my mind. Someone psychoanalyze me! Lol
