- sudhirj 5y agoFor single core workloads, probably. Didn’t we hit the clock speed cap around 2010?

- greatjack613 5y agoThere is a lot more in single core performance then just clock speed, in fact ipc is even more important then clock speed when it comes to single core computing
- bla3 5y agoBuilding a project isn't a single-core workload usually, though.
- grishka 5y agoIsn't C++ compilation mostly single-core-bound still? Of course it does compile as many files in parallel as there are cores, but it's not possible to compile a single file in multiple threads.
- khuey 5y agoYeah but most projects that have compile times long enough to care about have many source files.
- ohgodplsno 5y agoYou haven't seen most Android projects that have a massive legacy module that Gradle spends 5 minutes compiling and doing nothing else. Seeing those 7 lines say IDLE is a daily experience
- treefry 5y agoNot surprising as Moore's law had stopped applying to CPU. Assuming each year CPU gets 20% improvement, from 2012 to 2021 the latest cpu is 5x more powerful than the old one. Considering 30% performance loss for converting x86 instructions to ARM, 4x is a reasonable number.
