i have a feeling well see history repeat itself here just like how intel beat amd. intel might be behind on power consumption now against arm, but next generation will only get better. with the amount of money intel invests in R&D and power consumption, their next gen chips will definitely be a major improvement. intel uses their own 22nm process while arm is just now using 28nm, so intel has alot more room for improvement.
arm better stop barking because intels just gonna bite them in the ass harder. Im not trying to bash arm, theyre power consumption/performance is always getting better with every generation by alot. its just that, like a commenter already said, intel has so much money and smart people with them that they can invade any industry and be a success.
