I found this app that runs some benchmarks for the device and shows some CPU performance measures: https://apps.garmin.com/en-US/apps/7d836871-cf67-4963-b56b-1d81a7808ba0
I am trying to understand the meaning of the results. It uses a metric called "Pips". But what exactly does it mean in traditional terms? The traditional CPU performance metric I have heard before are FLOPS (floating point operations per second) and MIPS (million instructions per second). If Pips is like MIPS, then I don't know what prefix P stands for. And the description of the app says calculations Pi per second (Pi as in 3.14... ?), which still doesn't make total sense to me.
I would appreciate clarification, thank you!
