Yes look at their MT benchmarks of the 8/16 chip divide by two for the 4/8 chip and compare to i5-6400 running at 3.1Ghz all core turbo.
... because it will have 25-30% lower IPC then sky/kaby.
If it's priced the same as the i5-6400 it will basically just be another choice being not much worse overall but offering more threads,hardly anything to loose your mind over.
Only if you blindly believe AMDs PR talk does the ZEN look very good and worth waiting for.
I cant follow you calculations and neither can Canard themselves as they write it like it will shake up the market. And that Intel is a trainwreck. Perhaps the difference is they had the cpu in hand and interviewed employees and ex employees at Intel. Or perhaps they dont know the trick that you can just devide by 2 to go from 8c mt scores to 4 core results. Funky stuff but nice to see such software scaling. We need more of that
