The most surprising thing to me from AMD's ISSCC presentation is that, unlike what has been widely presumed, Zen 2 is not using the high-performance variant (HP) of the N7 process, but rather the high-density variant (HD). HD has 6 track standard cell height, while HP has 7.5 track standard cell height (see WikiChip). That goes some way to explain why the chips fell short of 5 GHz. It simply wasn't the priority it seems; density and power were more important.

PS. Could it be a typo on AMD's part? WikiChip repeats the 6T claim, though.
