entry level i3-4330 3.5 ghz@54watt TDP with HD4600 can easily beat AMD's newest offering Richland in pure x86 by a big difference.
on i5 side i5-4670k can easily beat AMD's top notch FX-8350 in half TDP(not consider igp's TDP coz FX does not have igp).
AMD simply have no match for i7 as i7 is 30-50% faster than FX-8350 in windows ecosystem coz windows is optimized for intel on linux difference is about 20%........i7 is still undefeated from first day.
AMD's upcoming steamroller core even can't beat i7 coz AMD says only upto 25% performance boost the only hope is AMD excavator and i think with excavator AMD can start battle for crown again coz excavator will be 25% more powerful than steamroller but excavator has much bigger hidden weapon i.e. support to discreet gpu HSA means adding a discreet gpu will increase whole systems performance by atleast 40% simply much better than intel's broadwell or skylake but i don't think this will happen soon coz HSA requires optimized ecosystem which we don't have and intel will not let that happen.
this all possible if there is no delay from AMD(Another Manufacturing Delay).
