Its pretty darn difficult to judge and its a bit of a stupid comparison in itself if TTM, designcost, sales volume, fmax and density of process is not taken into consideration. As is, its pretty meaningless.Thunderbolt and the IPU does take up a ton of space. AVX-512 and bfloat and all that does take up a little bit I imagine but it can't be that much... it's not like they added the second AVX-512 unit like they did with Skylake Server.
At the end of the day i would say margins is a better indicator if any, but we dont know those specific for those new apu. Surely earlier kbl 2c 4c must have had to be a good deal superior to amd solution raven or picasso as can be indicated by overall margins. I am pretty sure the Intel design is very efficient mm2 vise, as it have always been, but its to early to tell, and the compettition and therefore benchmark is quite different this time.
