This kind of thing really has nothing to do with Eve, but with Intel (not that you said otherwise, just making a statement). I get that Eve is new and still trying to figure a lot of things out, but Intel has been in the business for nearly 50 years. Sure, Intel makes their mistakes, but their chips almost always perform as designed.
The i7 Y is supposed to be more powerful than the i5 and m3, and for 99.5% of these processors that should be the case (provided every other variable is the same). There is still a ‘wafer lottery’, and sometimes you get lucky or you just get a dud - but as far as reliable processor performance Intel is pretty rock solid.
Also, I get that you may be a bit upset, but it’s probably not in the best taste to keep mentioning this.
