hi guys, got 2017 macbook i7 1.4ghz 16gb ram replace m7 1.3ghz 2015 macbook. ran 20minute benchmark try compare speeds in longer cpu tests.
using p7zip benchmark mode find 26.5% increase in cpu performance between 2017 & 2015.
it'd useful numbers 2017 i5 & m3 can compare sustained cpu benchmarks. can if you're comfortable in command line terminal shell.
1). install p7zip first install home-brew (https://brew.sh) running first command on command line.
a) /usr/bin/ruby -e "$(curl -fssl https://raw.githubusercontent.com/homebrew/install/master/install)"
b) brew update
c) brew install p7zip
2). close apps , let macbook idle 5 minutes or cool off above.
3). run benchmark on command line: 7z b 3 -mm=\*
takes 15-20minutes (we can make longer replacing 3 more iterations - think it's long enough).
copy paste last few lines. here's got:
