You are sooooo sooo wrong.
1)you can not compare clocks, different architectures. 4770K ussually ended at 4.4 GHz stable with air (too hot), FX Vishera 4.8 GHz ussually
2) Do you know, what are logical cores or not?Im sure, i7-4770K has 8 logical cores as FX-8xxx. And yes, i7 is 4C/8T. The core is here mainbuilding unit.
FX has not building unit the core, but THE MODUL UNIT (shared second cache, FP unit and few next limitation) ! So its 4CU/8T
Sadly if someone since 2004 experience dont know this basics ,-). 8 cores was unfortunately marketing of AMD for hype. Engineers dont wanted it with name 8-core.
But I think, this is at 99% lost. AMD can not fight with giant yet

...I think strategy will come back to APUs and HSA. Maybe in future 2-3 years will strike again with performance chips.
