So on 5NM each 8 core CCX is 69MM2. It also means Zen4 is 8 cores per CCX.

What size are zen 3 chiplets out of interest?

Thx
The WikiChip articles on Zen3 seems to be missing sizes and transistor counts (but their Zen2 do have this):
https://en.wikichip.org/wiki/amd/cores/cezanne
https://en.wikichip.org/wiki/amd/cores/vermeer
But the Apple A12/A13/A14/M1 ones do.
So both the 7nm A12 and A13 had 83 and 86 million transistors per mm².
The 5nm A14 and M1 are both 134 million transistors per mm².
An increase of 58%.
69mm to 80mm is a reduction in size of about 14% but with the increased that's another 36% transistors for Zen4.
Hope they've spent them wisely!
With the new potential to put L3 in 3D stacked chiplets, I would imagine that mainstream CCDs will stick to 32MB as higher end SKUs they can add a cache chiplet.

What? again? that has to be right at some point if its said often enough, i guess.
I should have laughed much harder and louder when Rocket Lake hit, but i though cheering for one over the other was very immature.
It was so tempting tho with all the "Rocket Lake will beat Zen 3" crap that was going on...
