debating which one. m3=7y32, i5=7y54 note that intel has rebranded the m-series as i only for the i5 and i7. hence when saying i5 and i7 i am referring to the Y series 7y54 and 7y75, not the 15w U-series kabys. i find it curious that 7y54 and 7y75 (4w kaby i5 and i7) along with kaby m3-7y30 (predecessor of m3-7y32 inside macbook 2017) all came out on Q3 2016 whereas m3-7y32 came out in Q2 2017. also from the spec sheet the i5 and i7 have same dimension, whereas 7y30 and 7y32 also have same domension but diffferent from i5 and i7. 7y54, 7y32 and 7y30 are all marketed same price 281$ whereas 7y75 393$. i have a feeling that the m3-7y32 inside the base macbook is overpriced and perhaps not as good as i5 or i7 despite better performance than 7y30. i feel that its almost like apple wanted a better cpu than the 7y30 for its base model but didnt want to pay more so intel just managed to tweek a few things on the same basic 7y30 and test it to function at higher frequencies. note that the i5 and i7 have lower tdp than 7y30 and 7y32 and, as stated before, different chip size. this is what makes me think the m3 inside the base macbook 2017 may not be on par with upper i5 (and i7). m3 is 1299$ i5 is 1599$ i know the i5 has double ssd aswell but strictly cpu oriented which one is worth more? alot of people say they are similar according to benchmark tests etc but im really sckepticle.
