It is indeed an Ivybridge i7 but it's a quadcore not duelcore, I replaced a duelcore with the quadcore and the performance difference is amazing, I don't think you can compare it with a Ryzen as they are not supported on a Mac and it's about the overall feel, the build quality of an aluminium case with an amazing keyboard Vs a plastic laptop has no comparison. An old Mac is like comparing a 2012 VW Golf which is expensive to purchase originally to a Fiat Punto, how many 2012 Fiat Puntos do you see today?
