The 10th generation CPUs are faster for a given clock speed, so it's unlikely the 2018 would be faster than the top end i7 2020 model. Regardless, I don't think I'll be replacing my 2.3 i5 2018 model with this round.I was wrong. Apple updated the 13" model with the magic keyboard..
Anyway, my 2018 Mbp is still great and has 2,7Ghz i7 CPU, which none of the new configurations is offering. Somehow I thing that my MBP is better (apart from the keyboard)..
