Skylake-SP area breakdown

I did some analysis a while back that might useful to share here.

8.0 mm2 SKL core
0.9 mm2 AVX512
2.0 mm2 1MB L2$
2.4 mm2 1.375MB L3$
0.4 mm2 Snoop filter
2.0 mm2 caching and home agent
2.2 mm2 FIVR, PLLs
0.4 mm2 Mystery block

18.0 mm2 Total SKL-SP tile

So AVX512 is about 5% of the tile area, the tiles are 72% of the total area of SKL-SP.

If you removed AVX512 you'd save 28mm2 for the whole chip, which would let you add at most 2 tiles.

In that vein, it seems like a pretty reasonable trade-off.
