If you are interested in looking into the details of microbenchmarks of this type, there is always https://benchmarksgame-team.pages.debian.net/benchmarksgame/... which has clearly defined methodology and allows to understand wall-clock time vs CPU cost too.

The benchmark code linked in the submission unfortunately suffers from the mistakes that happen whenever you write a benchmark for the first time. The visuals are pretty but might as well have been based on something more comprehensive.

(also, please stop measuring performance with loops that perform no work and fibonacci sequences, this was bad 30 years ago, this is bad today too)

Cool, thanks! In another lifetime I had an internship at an embedded software company which was to write tests and optimize compute or throughput for various chips and chip firmware, and reading the functions here sparked some alarm bells in my head. Still a fun idea though and cool graphics.
