I assume these are your models

MBP 2017 13" or MBP 2017 15"

MBP 2018

Based on the specs, yes the 2018 version is using recent tech compared to the 2017. I dont think that tech is worth RM1.5k though, especially for your use case. Just use the 2017 version or any other non Mac laptop for that matter, if youre not using it for any Mac specific software.
