>Even the E-cores draw more power than the M1/M2 cores. To be clear, this is also a product of the fabrication process and node size. Intel 12/13th gen are on Intel 7[1] - which is fairly old at this point, while M1s are fabricated on 5mm process[2]. Smaller lithography size isn't the whole story, but it certainly does make a difference
