We have seen many users doing *overlock* to know their *PIs* limit and not turn it into an ornament for your desktop.
*Benchmarks* allow us to know the computing power that has a *CPU/GPU* in general, and today I'll show you a command to check yours...
Credits goes to *Dinesh Auti*, which has developed a post to show how to use it.
Just run the next command called *bc* (binary calculator), which calculated the values of Pi with arbitrary number of decimals.
Mis apuntes de...
time echo 'scale=1000;4*a(1)' | bc -l
Curiously, the author of the article with an *raspberry Pi* without overlock has given the following results:
1000 decimal: 4 sec 37 milliseconds
2000 decimal: 24 sec 29 milliseconds
I remind you that you can know more technical details with the **nbench** tool, which is available for installation via [PiKISS](https://github.com/jmcerrejon/PiKISS/blob/master/scripts/info/bmark.sh).
