Risc architectures do have power efficiency advantages over cisc so I dont expect intels chips to really compete on power efficiency unless they develop a line of arm based chips also. I think that if they did build arm chips and design for energy efficiency I bet they could compete but I think they are likely to continue to push x86 for much of the future. I don’t really know though. Good question. I look forward to reading some other responses

I mean all mac laptops sifted from intel to arm so that’s like 20% of their market right there… that’s a dent.
