1.- AMD didn't release Steamroller or Excavator cores for FX line, but just into APU's. Just to save money for more important projects (Zen).
- AMD knew they don't have high performance manufacturing process anytime soon so they really cannot compete with high clock speeds. 14nm LPP is still very competitive on server/mobile market.
3. - AMD has much better GPU's than Intel has so AMD's integrated solutions are clearly superior (consoles...)
- AMD could do ARM chip whereas Intel, well, of course could but x86 market leader making ARM chip to compete with x86
