       | Maybe maybe maybe 4c is chiefly a process tweak, that going lower
       | power let them use more aggressive process scaling. Maybe. But
       | that's still a huge die-space reduction that makes me think

       | chipsandcheese.com was able to uncover with read deep
       | prying/benchmarking.

       | I do wish the graphs in this article had a comparison processor
       | or two. A regular Zen 3 would be great.
